Can Endler Guppies and Cherry Shrimp Breed Successfully Together?

October 10, 2026 · by Filip Sedlak · 5 min read

Yes, Endler guppies and cherry shrimp can absolutely breed together in the same tank. But “successfully” is doing some heavy lifting in that sentence, and it really comes down to three things: how big your tank is, how much plant cover you’ve got, and how much shrimp population loss you can live with. Endlers are small, peaceful livebearers that mostly leave adult shrimp alone. Give them the chance, though, and they’ll snack on newborn shrimplets without hesitation. Set things up right, and both species will thrive and multiply side by side for years.

Why This Combo Is So Popular

Endler guppies (Poecilia wingei) and cherry shrimp (Neocaridina davidi) are two of the friendliest species out there for beginners. Both share a handful of traits that make them easy to recommend:

• Small — Endlers max out around 1 to 1.5 inches; cherry shrimp stay under 1.5 inches too.
• Prolific breeders — females of both species reproduce constantly, no special triggers needed.
• Low-bioload — perfect for nano tanks, 5 to 10 gallons and up.
• Colorful — Endlers flash orange, green, and blue patterns, while cherry shrimp range from pale pink to a deep “fire red” that looks almost unreal under good lighting.

Since they occupy different zones of the tank (Endlers cruise the mid-to-upper water column while shrimp graze the substrate and plants), a lot of hobbyists figure they’re a natural match. In practice, that assumption holds up pretty well.

Will Endlers Eat Baby Shrimp?

Here’s the real question everyone’s actually asking. Adult cherry shrimp are usually too big, and too skilled at hiding, for Endlers to bother with. The danger is almost entirely limited to two situations:

• Shrimplets — freshly hatched shrimp are practically see-through and small enough to disappear into an Endler’s mouth in one gulp.
• Molting shrimp — soft-bodied and defenseless for a short window right after shedding their shell.

In a bare tank, or one with just a little greenery, Endlers can seriously stunt shrimp population growth by picking off babies the moment they show up. Drop a ton of plants in there, though, and shrimp colonies often explode anyway, simply because there’s too much cover for a handful of fish to patrol.

How to Set Up the Tank for Dual Breeding Success

1. Prioritize Dense Plant Cover

Java moss, Christmas moss, pogostemon, floating plants like frogbit or salvinia: all of these matter. Moss especially works like a nursery. Shrimplets burrow into it constantly, and it happens to host the biofilm and microorganisms they live on in those first few weeks.

2. Add Hardscape and Hiding Spots

Driftwood, rock caves, and those plastic mesh “shrimp tubes” give adults a safe place to molt and give berried (egg-carrying) females somewhere to disappear to when they need to.

3. Keep the Tank Mature and Stable

An established tank, one with a real biofilm layer and some healthy algae growth, gives shrimplets plenty to graze on. That means less time spent foraging out in the open, where an Endler can spot them in two seconds.

4. Don’t Overstock Fish

Stick to roughly 1 Endler per 2 to 3 gallons, leaning slightly female-heavy to cut down on male chasing, and predation pressure stays manageable. Once you see shrimp breeding well, resist the urge to add more fish. Overcrowding just ramps up the hunting pressure.

5. Feed Fish Adequately

A well-fed Endler has little interest in hunting shrimplets. Underfeeding, on the other hand, is one of the most common reasons fish start turning more aggressive toward shrimp fry.

Tank Size Recommendations

These numbers assume moderate to heavy planting. If your tank is more or less bare, scale the fish count down.

Water Parameters Both Species Share

Here’s the good news: Endlers and cherry shrimp want nearly identical water conditions, so there’s no real compromise to make.

• Temperature: 72 to 78°F (22 to 26°C)
• pH: 6.5 to 8.0
• GH: 6 to 8 dGH (shrimp actually do better with slightly harder water, since it helps with healthy molting)
• Stable parameters matter more than hitting an exact number. Avoid swings, even small ones.

Signs the Combo Is Working

• You’re spotting shrimplets of different sizes, not just full-grown adults, which means some of them are actually making it to maturity.
• Berried females show up regularly and aren’t hiding 24/7.
• The overall shrimp population keeps climbing over the months, even with the occasional loss here and there.

If the shrimp population seems stuck, or worse, shrinking, even though you keep seeing berried females, that’s a red flag that predation is outpacing reproduction. Time to toss in more moss, or cut back on the fish count.

Conclusion

Endler guppies and cherry shrimp genuinely can live and breed together in the same tank, and for a lot of hobbyists, this pairing turns into one of the most rewarding low-maintenance nano setups around. The goal was never to stop predation completely anyway; a few shrimplet losses are normal, even useful for keeping the population in check. What actually matters is stacking the odds in the shrimp’s favor: dense planting, well-fed fish, and sensible stocking numbers. Get that habitat dialed in, and chances are you’ll be watching both species multiply steadily for a long time to come.
