Consider this your ultimate endlers guppies care guide. Let’s get started on building your vibrant underwater world!
What Exactly Are Endlers Guppies?
Before we get into the nitty-gritty of care, let’s talk about what makes these little guys so special. Endlers, or Poecilia wingei, are not just small guppies; they are a distinct species with a unique history.
Originally discovered in Laguna de Patos in Venezuela by Dr. John Endler in 1975, these fish were thought to be extinct in the wild for a time before being rediscovered. This wild heritage gives them a robustness that you don’t always find in their more common guppy cousins (Poecilia reticulata).
Endlers vs. Common Guppies: What’s the Difference?
While they can interbreed (creating hybrids), there are a few key distinctions:
- Size: Endlers are noticeably smaller. Males rarely exceed 1 inch, while females top out around 1.8 inches. This makes them ideal for nano or smaller aquariums.
- Body Shape: Males have a more slender, streamlined body compared to the often bulkier fancy guppies.
- Fins: Common guppies have been bred for long, flowing fins. Endlers have shorter, more practical fins, often with brilliant pops of color.
- Color Pattern: Endler colors are often described as “pixelated” or mosaic-like, with intense, neon patches of orange, green, blue, and black. Their patterns are a hallmark of their species.
One of the main benefits of endlers guppies is their hardiness. They are incredibly forgiving of the minor mistakes that beginners often make, as long as their basic needs are met.
The Perfect Home: Your Endlers Guppies Tank Setup
Creating the right environment is the most critical step. Get this right, and you’re 90% of the way there. Don’t worry—it’s easier than you think! Here’s how to endlers guppies setup their home for success.
Tank Size and Why It Matters
Because of their small size, you can technically keep a small group in a 5-gallon tank. However, I strongly recommend starting with a 10-gallon tank, especially if you’re a beginner.
A larger volume of water is more stable. Water parameters (like ammonia and pH) don’t swing as drastically, giving you a much bigger buffer for error. Plus, Endlers are active swimmers and prolific breeders—they’ll appreciate the extra space!
Water Parameters: The Golden Rules
Endlers are adaptable, but they thrive in stable conditions. Chasing a “perfect” number is less important than keeping the water clean and consistent.
- Temperature: 72-82°F (22-28°C) is their sweet spot. A small, adjustable heater is a must to prevent temperature swings.
- pH: They prefer slightly alkaline water, from 7.0 to 8.5. Most tap water falls within this range.
- Hardness: Moderately hard to very hard water is ideal. They appreciate the minerals!
- Ammonia, Nitrite, Nitrate: This is non-negotiable. Your tank must be fully cycled before adding fish. This means you should have 0 ppm ammonia, 0 ppm nitrite, and some nitrates (ideally under 20 ppm).
Pro Tip: Get a reliable liquid test kit like the API Freshwater Master Test Kit. It’s far more accurate than test strips and will be your best friend in maintaining a healthy tank.
Filtration and Plants
Endlers come from calm waters, so they don’t appreciate a strong current. A gentle filter is best. A sponge filter is the perfect choice for an Endler tank. It provides excellent biological filtration, creates a gentle flow, and is completely safe for tiny fry.
Live plants are not just decoration; they are a core part of an Endler’s ecosystem. They help process nitrates, provide hiding spots, and offer surfaces for beneficial bacteria to grow. Great plant choices include:
- Java Moss
- Anubias Nana
- Java Fern
- Floating plants like Hornwort or Guppy Grass (fry love these for cover!)
A Healthy Diet for Vibrant Colors
You are what you eat, and the same goes for your fish! A varied, high-quality diet is the secret to bringing out those stunning, iridescent colors and promoting active behavior.
In the wild, Endlers are omnivores, constantly grazing on algae and tiny invertebrates. We want to replicate this in the aquarium.
What to Feed Your Endlers
A good feeding plan includes a mix of the following:
- High-Quality Flakes or Micropellets: This should be their staple food. Look for brands with whole fish or insect meal as the first ingredient, not generic “fish meal.” Crush flakes slightly to make them easier for their small mouths to eat.
- Frozen Foods: Offer these 2-3 times a week as a treat. Baby brine shrimp, daphnia, and cyclops are fantastic choices. They are packed with protein and nutrients.
- Live Foods: If you’re feeling adventurous, culturing your own baby brine shrimp or daphnia is the absolute best thing you can feed them. It triggers their natural hunting instincts and is incredibly nutritious.
Feed them once or twice a day, only giving them what they can completely consume in about 30-60 seconds. Overfeeding is one of the most common problems with endlers guppies as it quickly pollutes the water.
Behavior, Temperament, and Ideal Tank Mates
Endlers are a joy to watch. The males are constantly zipping around, flaring their fins at each other and displaying for the females. This isn’t usually aggressive; it’s more like a harmless dance to show off their colors.
The Ideal Male-to-Female Ratio
This is one of the most important endlers guppies best practices. The males have a one-track mind: breeding. To prevent females from getting exhausted or stressed from constant attention, you should always keep more females than males.
A ratio of one male to two or three females is perfect. This spreads the male’s attention around, ensuring no single female is harassed. If you want a male-only tank to enjoy the colors without breeding, that works great too! Just make sure there are no females present.
Peaceful Neighbors Only
Endlers are peaceful and will be bullied by larger or aggressive fish. Their small size makes them a potential snack for many species.
Excellent tank mates include:
- Pygmy Corydoras
- Otocinclus Catfish
- Small Rasboras (like Chili or Phoenix)
- Freshwater Shrimp (Cherry, Amano)
- Nerite Snails
Avoid: Bettas, most barbs, cichlids, angelfish, or any fish large enough to fit an Endler in its mouth.
Breeding Endlers: Get Ready for Fry!
If you have both males and females, you will have babies. Endlers are livebearers, meaning the females give birth to free-swimming fry rather than laying eggs. It’s incredibly easy and fascinating to watch.
The female gestation period is about 23-28 days. She will look very boxy and develop a dark “gravid spot” near her anal fin. One day, you’ll simply look in your tank and see dozens of tiny specks darting around!
To ensure the fry survive, provide lots of cover. Dense clumps of Java Moss or floating plants like Hornwort are perfect hiding places. The parents will eat their young if they can catch them, but Endlers are generally less aggressive towards their fry than common guppies.
You can feed the fry crushed-up flake food, or for faster growth, newly hatched baby brine shrimp.
Sustainable and Eco-Friendly Endler Keeping
Being a responsible aquarist is part of the fun. Embracing sustainable endlers guppies practices is not only good for the planet but also creates a healthier, more balanced aquarium.
The best way to do this is to create a thriving, self-sufficient colony. A well-planted tank with a healthy population of Endlers is a beautiful example of a miniature ecosystem. The plants use fish waste as fertilizer, and the fish enjoy the security and oxygen the plants provide.
Another key part of eco-friendly endlers guppies keeping is population management. Since they breed so readily, you must have a plan for the fry. Options include:
- Letting nature take its course (some fry will be eaten, keeping numbers stable).
- Selling or trading them with a local fish store or aquarium club.
- Rehoming them to fellow hobbyists online or in your community.
Never release any aquarium fish into local waterways. They can become invasive and devastate native ecosystems.
Common Problems with Endlers Guppies (And How to Solve Them!)
While hardy, Endlers aren’t invincible. Nearly all problems can be traced back to one thing: water quality. Here are a few issues to watch for.
Ich (White Spot Disease)
This looks like tiny grains of salt sprinkled on your fish’s body and fins. It’s a common parasite, usually triggered by stress from poor water quality or temperature fluctuations. To treat it, slowly raise your tank temperature to 82-84°F (28-29°C) for a week and perform more frequent water changes.
Fin Rot
If you see ragged, decaying, or discolored fins, it’s likely fin rot. This is a bacterial infection caused by dirty water. The cure is simple: clean water. Perform a 30-50% water change immediately and continue with smaller, more frequent changes until the fins begin to heal.
Overpopulation
As we discussed, this is a real possibility! The best solution is prevention. Start with a proper male-to-female ratio or a male-only tank if you don’t want to deal with fry. Have a plan in place to rehome excess fish.
Frequently Asked Questions About Endlers Guppies
How many Endlers can I keep in a 10-gallon tank?
A good starting point for a 10-gallon tank is a trio (1 male, 2 females) or a small group of 5-6 males. Remember that if you have females, that number will multiply quickly! A heavily planted and well-filtered 10-gallon can comfortably house a colony of 15-20 adult Endlers.
Can Endlers live with regular guppies?
Yes, they can live together peacefully. However, they will interbreed. The resulting offspring are hybrids and, while often beautiful, they are no longer pure Endlers or pure guppies. If you want to maintain a pure Endler line, do not keep them with common guppies.
Are Endlers good for beginners?
Absolutely! They are one of the best beginner fish available. Their hardiness, small size, and active nature make them incredibly rewarding and forgiving. This complete endlers guppies guide gives you everything you need to start off on the right foot.
Why are my Endlers losing their color?
Dull color is almost always a sign of stress. The most common causes are poor water quality (check your ammonia, nitrite, and nitrate levels!), an improper diet, or harassment from other fish. Address these issues, and their vibrant colors should return.
