Shrimp Tank Mates Guide

"What can live with my shrimp?" is one of the first questions every new shrimp keeper asks — and the honest answer is less than you'd hope. To most fish, a tank full of dwarf shrimp looks like a tank full of free snacks. Picking tank mates is really an exercise in damage control: choosing companions small and peaceful enough that your colony survives, and ideally keeps breeding.

The core rule: most fish eat baby shrimp

Adult cherry shrimp are big enough that many small fish leave them alone. Shrimplets are not. Their tiny size, as Aquarium Co-Op puts it, makes them "irresistibly delicious" to other fish. That single fact drives every tank-mate decision: a fish can be perfectly peaceful toward adults and still quietly wipe out every baby, so the colony never grows.

This is why the gentlest, smallest-mouthed fish are the only fish worth considering — and why a species-only tank is still the gold standard if breeding matters to you. You can sanity-check any stocking idea with our Stocking Calculator before you buy.

Shrimp tank mate compatibility at a glance

Here is every common community species rated against a dwarf-shrimp tank. The verdict comes straight from the same compatibility logic behind our Stocking Calculator, and each row links to the care reference it is based on.

The safe tank mates

Snails are the best companions, full stop. They are scavengers and detritivores that ignore living shrimp completely while helping clean the tank. Any of these work:

• Nerite snails — the algae-eating champion, and completely shrimp-safe
• Mystery snails — larger, peaceful, and colorful
• Bladder and Malaysian trumpet snails — tiny cleanup crew that breed on their own

Other shrimp and inverts also coexist peacefully:

• Amano shrimp — larger algae-eaters that won't bother cherry shrimp
• Bamboo (wood) shrimp and vampire shrimp — gentle filter feeders
• Thai micro crabs — tiny, harmless, and fascinating

If you want fish, stick to micro-mouthed nano species:

• Chili rasboras — tiny, peaceful, and a hobby favorite for shrimp tanks
• Ember tetras and green neon tetras — small and gentle
• Pygmy corydoras — bottom dwellers that mostly ignore shrimp

Even with these, expect some shrimplet losses. They are the lowest-risk fish, not zero-risk.

A sponge filter matters even more in a community tank: it filters without an intake tube that could suck in shrimp or babies, which a hang-on-back or canister filter readily does.

The fish to avoid

These will hunt adult shrimp, not just the young, and have no place in a shrimp tank:

• Goldfish — messy, and will eat anything that fits in their mouth
• Cichlids and dwarf cichlids — predatory by nature
• Dwarf gouramis and bettas — often treat shrimp as live food
• Pea puffers — dedicated invertebrate hunters; shrimp are their natural prey
• Rainbowfish, larger plecos, zebra danios, silver tip tetras — fast, nippy, or big enough to be a constant threat

If a fish is bigger than about an inch and a half, fast, or known to eat invertebrates, assume it is not shrimp-safe.

A safe tank mate also has to share the water. A non-predatory fish is still a bad match if it needs different conditions than your shrimp — coldwater fish like goldfish are wrong on temperature as well as appetite, and soft-acidic Caridina shrimp pair with a different fish list than neutral-to-hard Neocaridina. Match temperature and hardness first, then filter that list down to the gentle, micro-mouthed species above.

"Surviving" is not the same as "thriving"

Here is the nuance most tank-mate lists skip. People keep guppies or tetras with cherry shrimp and report it "works" — and it does, in the sense that the adults survive. But watch the population over six months: it stays flat or shrinks, because every shrimplet that ventures into open water gets eaten. The colony isn't thriving, it's just being topped up by the occasional baby that survives.

If your goal is a growing, breeding colony, the only reliable answer is a species-only tank. If you simply want a few shrimp adding color and cleanup to a peaceful community tank, a mixed setup is fine — just go in expecting a static population, not a population boom.

Give the babies somewhere to hide

In any mixed tank, dense cover is what tips the odds toward the shrimp. A thick thicket of Java moss, piles of rock, driftwood, and dedicated shrimp caves give shrimplets places to disappear during their most vulnerable first weeks. The more cover you provide, the more babies survive to adulthood — sometimes enough to keep even a community colony slowly growing.

The bottom line

For a thriving, breeding colony, keep shrimp on their own or with snails. For a community tank, choose the smallest, gentlest fish you can find, plant heavily, and accept a steady rather than growing population.
