Choosing the Right Tank Size

Choosing the Right Guppy Tank Size

Ah, guppies! These vibrant, darting creatures are the confetti of the aquarium world, aren’t they? When it comes to giving them a place to call home, space does matter.

Let’s wade into the depths, shall we?

For a single guppy, a tank of at least 5 gallons is recommended. This gives our little friend ample room to swim, forage, and just be its playful self. But here’s the fascinating bit: guppies are sociable critters. They thrive in the company of their own kind, and their vibrant colors and playful behaviors truly come alive in a group. It’s like watching an underwater ballet, with each dancer having its unique rhythm and flair.

If you’re considering adding more guppies to your tank, think of it this way: for every additional guppy, you should aim for an additional 1-2 gallons of water. So, if you’re thinking of a group of 5 guppies, a tank size between 10 to 15 gallons would be ideal.

But remember, while these are the bare minimums, there’s a lot to be said about guppy dynamics. In a larger space, guppies tend to be more active, exhibit richer colors, and have a lower risk of stress. In the world of fish, stress isn’t just a mental state; it can predispose these tiny beings to diseases and shortened lifespans. So, always consider their comfort.

Drifting deeper into our aquatic journey, let’s talk size. As with many things in life, bigger can indeed be better when it comes to the world of aquariums. And for our starry-eyed guppies, a roomier abode offers a plethora of benefits. Let’s dive in!

Space to Explore: First and foremost, more water volume provides a grander stage for our guppies to explore. These curious little creatures love investigating every nook and cranny, so a bigger tank offers a richer environment for them to satiate their natural wanderlust.

Stability: Here’s an interesting tidbit — larger tanks are inherently more stable when it comes to water parameters. Sudden changes in temperature, pH, or toxin levels can be detrimental to our aquatic friends. In larger volumes of water, these fluctuations are buffered, making it easier to maintain consistent water quality.

Reduced Stress: Fish, including guppies, have territories, social hierarchies, and, believe it or not, personal bubbles. In a spacious tank, there’s less competition for food, hiding spots, and mates. Less competition translates to less stress, and less stress means healthier, happier guppies. It’s like us humans having our own little corner in a bustling coffee shop – it’s simply comforting.

Flexibility: A bigger tank gives you, the aquarist, more room to play. Think about it. More space for plants, decorations, and even the possibility of introducing new tankmates. It’s a canvas waiting for your touch, a slice of nature ready to be molded.

Better Filtration: Larger tanks often come equipped with better filtration systems, or at least the capacity for them. Efficient filtration is paramount for guppy health as it keeps the water clear, removes harmful toxins, and provides a gentle current that our guppies love to play in.

Visual Impact: Lastly, on a slightly self-serving note, larger tanks, especially when well-maintained and adorned, can be show-stoppers in a room. They serve as windows into a watery realm, mesmerizing guests and offering you a peaceful escape from the hustle and bustle of daily life.

Substrate Selection

Guppy Substrate Selection

Ah, the age-old debate of gravel versus sand! Both substrates, like unique tapestries, have their merits and downsides. Let’s sift through the details, shall we?

Gravel: The Rocky Road

Pros:

  1. Ease of Maintenance: Gravel is relatively easy to clean. With a simple aquarium vacuum, debris sitting atop the gravel can be siphoned off with minimal fuss.
  2. Variety: Available in an array of colors and sizes, gravel lets your creative side shine, allowing you to customize your aquarium’s aesthetic to your heart’s content.
  3. Water Flow: Gravel facilitates better water flow, preventing the formation of anaerobic pockets, which can produce harmful gases.

Cons:

  1. Food Trap: Gravel’s larger gaps can cause food particles to sink and become trapped, leading to potential water quality issues if not regularly cleaned.
  2. Planting Difficulties: Aquatic plants with delicate root systems might find gravel a bit challenging to anchor into.

Pros:

  1. Natural Look: Sand offers a soft, smooth, and natural appearance that many aquarists find serene and reminiscent of many aquatic habitats.
  2. Better for Burrowers: If you ever wish to add bottom dwellers or creatures that like to burrow, sand is the ideal substrate. It’s gentle on their undersides and allows them to display natural behaviors.
  3. Less Food Waste: Fine-grained sand prevents food from sinking deep, so guppies and other fish can forage on its surface.

Cons:

  1. Compaction: Over time, sand can compact, potentially leading to anaerobic pockets which can produce harmful gases. It requires occasional stirring to prevent this.
  2. Clouding: When initially added or if stirred up, sand can cause temporary cloudiness in your aquarium’s water.

As we delve deeper, quite literally, into the topic of substrates, it’s imperative to understand the importance of depth. Whether you opt for the rustic touch of gravel or the serene embrace of sand, the depth of the substrate plays a pivotal role in the well-being of your aquatic sanctuary.

Planting Considerations: If you have visions of a lush underwater garden for your guppies to frolic in, substrate depth is crucial. Most aquatic plants need at least 2 to 3 inches of substrate to comfortably anchor their roots. For plants with extensive root systems or those that are particularly heavy feeders, aiming for a depth closer to 3 to 4 inches can be beneficial. This ensures they have ample room to spread out and absorb the nutrients they require.

Guppy Comfort: While guppies aren’t known for being bottom dwellers or burrowers, they do appreciate a well-structured and stable environment. A substrate depth of 1 to 2 inches is usually adequate for tanks that don’t house plants. This ensures a comfortable environment and reduces the chances of the substrate being stirred up too easily, which can cloud the water.

Maintaining Balance: A deeper substrate can sometimes harbor debris, uneaten food, and waste, especially if it’s not cleaned regularly. This can lead to the formation of harmful gas pockets, particularly in sand. Regular maintenance, like vacuuming gravel or gently stirring sand, is paramount in deeper substrates to prevent the buildup of these anaerobic zones.

Aesthetic Appeal: Depth isn’t just about function; it’s also about form. A well-layered substrate can create a sense of depth and perspective in your aquarium, drawing the viewer’s eye and making the tank look larger and more dynamic. Some aquarists even employ a sloping technique, where the substrate is deeper at the back and shallower at the front, creating a mesmerizing sense of depth.

Filtration System

Guppy Filtration System

Filtration – the silent guardian of our aquariums. You know, as I often say, an aquarium without a proper filtration system is like a forest without trees. It just doesn’t quite make sense. Filtration, in its essence, is the heartbeat of our water worlds, working tirelessly to ensure our guppies and other aquatic inhabitants have the purest and healthiest environment to thrive in. Let’s embark on this cleansing journey.

Clear Waters Ahead: A well-functioning filter removes particulate matter, debris, uneaten food, and fish waste from the water, ensuring that it remains crystal clear. This not only enhances the aesthetic appeal of the tank but also ensures our guppies have a clean environment to swim in.

Breath of Fresh Water: Fish, like all living beings, produce waste. This waste breaks down into ammonia, which is quite toxic to fish. A good filtration system hosts beneficial bacteria, nature’s tiny janitors, which convert this ammonia into less harmful compounds – nitrite and then nitrate. This process, known as the nitrogen cycle, is paramount for the health of your aquatic pets.

Oxygen Boost: As water circulates through the filter, it aids in oxygen exchange, ensuring that your fish always have a fresh supply of oxygen to breathe. Guppies might not have lungs like us, but oxygen is still crucial for their survival.

Stability is Key: A stable environment is essential for fish. A filtration system helps maintain a consistent water quality by removing toxins and pollutants. It acts as a buffer, preventing sudden and harmful fluctuations in water parameters that can stress out our delicate guppies.

Guard Against Disease: Clean water isn’t just about looks. By removing harmful compounds and potential pathogens, a filtration system can greatly reduce the risk of diseases in your tank.

Holistic Health: Just as we humans need a balanced diet, exercise, and fresh air, our aquatic friends need balanced water conditions. A filter contributes significantly to this balance, promoting overall well-being, vibrant colors, and active behaviors in our fish.

For our guppies, the filter plays multiple roles, so ensuring you select the right one is key to a harmonious underwater world.

Size Does Matter: Start by examining the size of your tank. Generally, you’d want a filter that can handle the entire volume of your tank at least 3-4 times every hour. For instance, for a 20-gallon guppy tank, aim for a filter rated at 60-80 gallons per hour (GPH).

Gentle Flow: Guppies, with their beautiful flowing fins and delicate nature, aren’t strong swimmers. A filter that generates a gentle current is ideal, allowing them to swim gracefully without struggling against forceful water movement. Canister filters and sponge filters are often favored for their ability to provide such gentle flows.

Three-Stage Filtration: To ensure optimal water quality, a filter should offer mechanical, chemical, and biological filtration.

  • Mechanical filtration traps physical debris like uneaten food and plant matter.
  • Chemical filtration, often through activated carbon, helps remove toxins and odors from the water.
  • Biological filtration provides a home for beneficial bacteria that break down harmful ammonia and nitrites. This is paramount for the nitrogen cycle we talked about earlier.

Maintenance Considerations: Some filters require more regular upkeep than others. For those who don’t wish to be too hands-on, filters with easy-to-change cartridges or media might be preferable.

Noise Level: Believe it or not, the hum or buzz of a filter can either be a soothing backdrop or an annoying disturbance. Consider the placement of the aquarium and your personal noise tolerance when selecting a filter.

Future Prospects: If you’re contemplating expanding your guppy family or even introducing new tankmates down the line, investing in a slightly larger filter now can save you from future upgrades.

Aesthetic Element: Some filters, like internal filters or under-gravel filters, are more discreet, blending seamlessly into the tank’s design. If you’re aiming for a natural-looking aquascape, such filters can be advantageous.

Water Conditions and Chemistry

Guppy Water Conditions and Chemistry

As we dive into the warm waters of this topic, I can’t help but reflect on the beautiful symphony of nature. Just as every creature on land has its favored climate, our aquatic companions too have their preferred temperatures. Guppies, with their vibrant colors and lively nature, are no exception. So, let’s explore the cozy comfort zone of these tropical treasures.

The Tropical Touch: Guppies hail from the warm waters of South America. In their natural habitats, they bask in temperatures ranging from 74°F (23°C) to 82°F (28°C). This is the range in which they truly thrive, showing off their best colors, behaviors, and health.

Ideal Conditions: To strike the right chord for your guppy family, aim for a sweet spot around 78°F (25.5°C). This ensures a comfortable, stress-free environment that mirrors their tropical homes.

Too Hot to Handle: Overly warm waters, above 82°F, can speed up a guppy’s metabolism. While this might sound beneficial, it actually means they age and wear out faster. Moreover, higher temperatures can reduce oxygen levels in the water, which can be detrimental.

The Chill Factor: On the flip side, temperatures below 74°F can slow their metabolism, making them less active and even a bit lethargic. It can also weaken their immune systems, making them more susceptible to diseases.

Steady Does It: While guppies are adaptable and can endure minor fluctuations, sudden changes in temperature can be incredibly stressful. It’s important to ensure a stable environment. An aquarium heater with a thermostat can be a great asset in this regard, especially if you live in an area with variable climate conditions.

Monitor & Maintain: Regularly check the temperature using a reliable aquarium thermometer. It’s a small investment that can make a world of difference in maintaining the optimal conditions for your finned friends.

Just as a wine’s character can be defined by its acidity or tannins, the health and vibrancy of our guppies can be influenced by the pH and hardness of their aquatic environment.

The Scale of pH: The pH scale measures how acidic or alkaline water is, ranging from 0 (most acidic) to 14 (most alkaline), with 7 being neutral. Now, guppies are quite adaptable, but they prefer a pH that leans slightly alkaline, typically between 6.8 and 7.8. Within this range, their colors pop, their fins flutter with gusto, and their health remains robust.

Understanding Hardness: When we talk about water hardness, we’re referring to the amount of dissolved minerals, predominantly calcium and magnesium. This is categorized into two:

  • GH (General Hardness): Measures the total mineral content. Guppies typically prefer moderate to hard water, which usually falls between 100-200 ppm (parts per million).
  • KH (Carbonate Hardness): This dictates the water’s ability to buffer and resist pH changes. A higher KH means more stability in pH levels.

Balancing Act: While guppies are quite resilient and can adapt to various water conditions, sudden changes in pH or hardness can stress them out. It’s essential to maintain stability, even if the numbers aren’t “perfect.” Aim for slow and gradual adjustments if necessary.

Natural Adjustments: If you wish to alter the pH or hardness:

  • To increase pH and hardness, consider adding crushed coral or limestone to the substrate or filter.
  • To decrease pH, driftwood or peat moss can be beneficial, as they release tannins that soften water and mildly acidify it.

Testing Waters: Regularly testing your aquarium’s pH and hardness levels is vital. Water testing kits are readily available and provide invaluable insights into your aquarium’s water chemistry.

Source Considerations: Remember, the water source can influence pH and hardness. Tap water in some regions may be hard or have a high pH, while in other areas, it might be softer or more acidic.

Navigating through the world of aquariums, there’s a particular journey that stands out – the voyage of tank cycling. Much like a river finding its course or a tree laying down its roots, establishing a stable environment in your aquarium is a dance of nature, patience, and understanding. Let’s embark on this crucial chapter in our guppy guidebook.

The Nitrogen Cycle – Nature’s Ballet: At its core, the nitrogen cycle is nature’s way of recycling waste. Fish produce ammonia, which is quite harmful. Beneficial bacteria come into play here, converting this ammonia into nitrite and eventually into the much less harmful nitrate. It’s like a relay race where each participant plays a critical role, ensuring a safe and thriving environment for our finned friends.

Starting from Scratch: If you’re setting up a new tank, it’s essential to cycle it before introducing your guppies. This means setting up the aquarium, filter, and substrate, then allowing beneficial bacteria to establish and mature.

Fishless Cycling: This is the preferred method, as it ensures no fish are harmed or stressed during the process.

  1. Add a source of ammonia, either pure ammonia or fish food.
  2. Test the water regularly. You’ll first see a rise in ammonia, then nitrite, and finally nitrate.
  3. Once ammonia and nitrite levels drop to zero and you have detectable nitrates, your tank is cycled and ready for guppies.

The Patience Game: Cycling can take anywhere from a few weeks to over a month. It’s a testament to the saying, “good things come to those who wait.”

Boosting the Process: There are bottled bacteria products available that can help kickstart the cycle. While not a replacement for natural cycling, they can accelerate the process and provide a foundation for bacterial colonies.

Monitoring is Key: Even after the initial cycle, it’s good practice to keep an eye on ammonia, nitrite, and nitrate levels. Regular testing can alert you to potential issues before they become problematic.

Partial Water Changes: Once the tank is cycled, performing regular water changes helps keep nitrate levels in check, ensuring a healthy environment for your guppies.

A Gentle Reminder: While our guppies are resilient and adaptable, an uncycled tank can be harmful, even fatal. It’s crucial to ensure the cycle is complete before introducing them to their new home.

Tank Decorations and Plants

Guppy Tank Decorations and Plants

Think of your tank as a blank canvas, and the decorations as brush strokes, creating a picturesque environment for your finned companions. But, as we dive into this realm, safety must be our guiding star.

Smooth Sailing: Guppies have delicate fins that can easily tear. Therefore, any decorations added should have smooth edges. It’s always a good practice to run your fingers over any new addition to check for sharp or rough areas. If it can snag a pantyhose, it might snag a guppy’s fin.

Natural vs. Manufactured: Natural decorations like driftwood, stones, and shells can be great additions. Ensure they are thoroughly cleaned and, if possible, boiled or soaked to remove any potential contaminants. Manufactured decorations, especially those designed for aquariums, are usually safe. Still, it’s wise to choose those that don’t have small openings where guppies might get stuck or trapped.

A Peek into the Past: Some hobbyists love adding themed decorations, like sunken ships or ancient ruins. They can create an enchanting underwater world. Just ensure these items are made from non-toxic, aquarium-safe materials.

Caves and Hideaways: Providing shelters can offer guppies a sense of security and places to rest. If using caves or similar structures, make sure the openings are spacious enough for guppies to enter and exit without difficulty.

Function with Form: Some decorations can serve dual purposes. For instance, clay pots or tubes can be both aesthetically pleasing and functional hideouts.

Plant Considerations: Plants, whether live or artificial, should also be safe. Opt for plants with soft leaves. Live plants have the added advantage of improving water quality and offering natural shelter.

Maintenance & Cleaning: Over time, algae and debris might accumulate on your decorations. Regular cleaning, using safe methods, ensures the aesthetic and health of your tank remain pristine.

Pros:

  • Natural Filter: They absorb waste products, like ammonia and nitrites, purifying the water and keeping our guppies healthier.
  • Oxygen Suppliers: Through photosynthesis, live plants release oxygen, which benefits all aquatic inhabitants.

Cons:

  • Static Environment: They don’t grow or contribute to water chemistry, making the tank’s environment relatively static.
  • Cleaning: Algae might grow on them, necessitating periodic cleaning.
  • Lack of Authenticity: While many look real, they can’t replicate the full benefits of live plants.

As serene as it may sound, for smaller creatures, this openness can be quite daunting. In the underwater realm of our guppies, this sentiment holds true. Just as we humans seek a cozy nook to retreat to after a long day, guppies too need their secret corners and hideaways.

Why Hiding Spots?

  • Safety Net: Hiding spots offer a sense of security, especially in community tanks where larger or more boisterous fish might be present.
  • Stress Reduction: Stress isn’t just a human phenomenon; fish feel it too! A secure place helps reduce their anxiety levels.
  • Breeding Grounds: If you have intentions of breeding, secluded areas offer guppies a private space for courtship and rearing fry.
  • Rest & Respite: Just as we have our beds, guppies need a spot to relax and rejuvenate.

Natural Hideaways

  • Plants: Dense plants, like Java moss or Anubias, offer excellent natural refuges. Their leaves and stems weave a labyrinth where guppies can dance and dart.
  • Driftwood: Their twisted, organic structures create alcoves and overhangs, perfect for a quick hide or a prolonged rest.
  • Caves & Rocks: Arranging rocks to form small caves or crevices can serve as a sanctuary. Ensure there are no sharp edges, and the entrance and exit points are spacious enough.

Man-made Hideouts

  • Decorations: Many aquarium decorations, such as castles, barrels, or themed structures, come with built-in hiding places.
  • PVC Pipes: A simple and effective solution. PVC pipes, especially when buried slightly in the substrate, provide an excellent hideaway.
  • Terra Cotta Pots: Laying a pot on its side or using broken pot pieces (with smoothed edges) can create a rustic retreat.

Strategic Placement

  • Zonal Retreats: Place hiding spots throughout the tank — some near the surface, some in the mid-section, and some at the bottom, ensuring guppies have retreat options irrespective of where they are.
  • Visibility: While it’s essential to have hideaways, ensure you can still see most of the tank and enjoy your guppies. Balance is key.

Maintain Accessibility

  • Space Them Out: Ensure the hideouts don’t congest the tank. Guppies should be able to swim freely without feeling boxed in.
  • Easy Cleaning: Place hiding spots in a manner that allows for easy maintenance and cleaning without disturbing the entire setup.

Lighting for the Guppy Tank

Lighting for the Guppy Tank

As the sun rises, casting its golden hues upon the water’s surface, or as the gentle glow of a lamp illuminates the aquatic ballet below, light plays a pivotal role in the theater of our aquarium. Both natural and artificial light have their merits and considerations, so let’s delve into this luminous chapter of our guppy’s world.

Pros:

  • Synchronization: Natural light cycles can help regulate the internal clocks of our guppies, syncing them with day-night rhythms.
  • Cost-effective: Utilizing sunlight means reduced electricity costs, and let’s be honest, there’s a certain charm in sunlight-dappled waters.
  • Plant Growth: For those with live plants, sunlight promotes healthy growth (though be mindful of the intensity and duration).

Cons:

  • Temperature Fluctuation: Direct sunlight can lead to rapid temperature spikes in the aquarium, possibly causing stress to guppies.
  • Algae Blooms: Sunlight can encourage excessive algae growth, leading to murky waters and potential imbalances.
  • Inconsistent Exposure: Depending on the season and location, the amount of sunlight your tank receives can vary.

Pros:

  • Control: You dictate the intensity, duration, and even color spectrum of the light, creating the perfect ambiance for your guppies.
  • Stability: No worries about sudden temperature changes or fluctuating light levels.
  • Tailored for Plants: Specialized lights, like full-spectrum or LED lights, can be selected to promote plant growth and health.

Cons:

  • Electricity Costs: While many modern aquarium lights are energy efficient, they still contribute to the electricity bill.
  • Maintenance: Bulbs can burn out or degrade over time, requiring replacement.

In the ever-evolving symphony of the aquarium, lighting plays a key movement. It’s not just about the type of lighting, but the length of its performance. So, how long should the lights in our guppy tank be on? Let’s explore.

Understanding Guppy’s Natural Rhythm

In the wild, guppies are accustomed to the rhythmic dance of the sun and moon, experiencing natural day-night cycles. Ideally, we aim to mimic this in the cozy confines of our aquarium, balancing the guppies’ needs with those of plants and the overall health of the tank.

Duration Recommendations:

  • For Tanks Without Live Plants:
    • 8-10 hours a day: This provides guppies with a sense of regularity, allowing them to engage in active behaviors during the “day” and rest during the “night.”
  • For Tanks With Live Plants:
    • 10-12 hours a day: Plants, my dear aquatic gardeners, rely on light for photosynthesis. A longer duration supports their growth and health, but be cautious not to overdo it lest we encourage unwanted algae.

Taming the Twilight with Dimmers: For those of you with advanced lighting systems, consider using dimmers to recreate the gentle rise and fall of natural light, offering a more graduated transition between day and night. It’s a subtle touch, but one that adds a layer of authenticity to the tank.

The Role of Timers: Ah, the modern marvels of technology! Using a timer ensures consistent light cycles, even if your daily routine varies. Set it and let it work its magic, orchestrating the day-night ballet in your aquarium.

Beware of Over-lighting: While our finned friends appreciate a well-lit stage, an overly long performance can lead to stress. Moreover, excessive light can spur algae growth, turning your pristine waters into a murky green.

Night Lights: Some aquarists enjoy using soft, blue-toned lights for nighttime viewing. If you choose to employ these, ensure they’re subtle and don’t disrupt the guppies’ rest.

Tankmates: Who Can Share the Space

Guppy Tankmates Who Can Share the Space

The vibrant jesters of the aquarium realm, darting about with their rainbow-hued tails and playful demeanor. But a jester doesn’t always perform solo; sometimes, they share the stage. The question is, with whom? Let’s dive into the realm of tankmates that can harmoniously cohabit with our guppy stars.

1. Corydoras Catfish:

  • Why They’re Compatible: These bottom dwellers are peaceful, ensuring the water column’s middle and lower zones are bustling with life.
  • Bonus Point: They’re excellent janitors, helping keep the substrate clean.

2. Mollies:

  • Why They’re Compatible: Like guppies, mollies are livebearers and share similar temperaments and care needs.
  • Friendly Tip: Opt for smaller molly species to ensure they don’t dominate the tank.

3. Platies:

  • Why They’re Compatible: Platies are peaceful, colorful, and share many of the same environmental requirements as guppies.
  • Note: Mix and match colors for a vibrant display.

4. Neon and Cardinal Tetras:

  • Why They’re Compatible: These schooling fish add a dash of shimmering color and are generally peaceful.
  • Aquascape Idea: Their iridescent blues and reds complement guppy colors beautifully.

  • Care Tip: Ensure you have enough algae or supplement their diet with algae wafers.

7. Dwarf Gourami:

  • Why They’re Compatible: Their calm demeanor and captivating appearance make them a delightful addition.
  • Remember: Gouramis prefer densely planted tanks for hiding and exploring.

While our guppies might be social butterflies (or should I say, fish?), not every underwater dweller is a suitable companion for them. Like a thoughtful director, we must carefully curate our ensemble to ensure the stars aren’t overshadowed—or worse, harmed.

1. Cichlids:

  • Why Avoid: Most cichlids are territorial and can be quite aggressive. Their penchant for staking out domains might put our guppies at risk.
  • Note: There are smaller, more peaceful cichlids, but general caution is advised.

2. Bettas (Siamese Fighting Fish):

  • Why Avoid: The bright colors and flowing fins of male guppies might provoke the territorial and sometimes aggressive nature of bettas.
  • Exception: Female bettas are less aggressive, but caution is still paramount.

3. Larger Barbs (like Tiger Barbs):

  • Why Avoid: They have a reputation as fin-nippers, and those glorious guppy tails might be too tempting to resist.
  • Friendly Tip: If you’re keen on barbs, consider smaller, less nippy species.

4. Larger Catfish (like the Red-Tailed Catfish):

  • Why Avoid: Their size and appetite mean that smaller tankmates, including guppies, might end up as unintended snacks.

5. Goldfish:

  • Why Avoid: Goldfish require different water conditions and temperatures than guppies. Moreover, their larger size and feeding habits can lead to complications.

6. Predatory Species (like Arowanas or Puffers):

  • Why Avoid: It might sound obvious, but these hunters see smaller fish as prey, not pals. Our guppies would be in perpetual danger.
