The safest choice
A shrimp-only aquarium gives the best colour, confidence and breeding rate. Bladder snails are excellent companions because they ignore healthy shrimp and graze leftover food and biofilm.
Fish with the lowest risk
Very small, peaceful fish such as chilli rasboras may coexist with adult shrimp in a densely planted tank. Otocinclus are generally peaceful grazers. Even these fish may take newly hatched shrimplets, so provide moss, fine plants, leaf litter and wood.
Honest answer: there is no completely shrimplet-safe fish. A mouth large enough to catch a baby shrimp may eventually do so.
Tank mates to avoid
- Bettas, gouramis and cichlids
- Goldfish and larger barbs
- Puffers and loaches that hunt invertebrates
- Crayfish and predatory crabs
- Large or aggressive fish of any kind
How to improve survival
- Add Java moss and dense stems before shrimp.
- Allow biofilm to mature for several weeks.
- Feed fish well without leaving excess food.
- Cover filter intakes with sponge.
- Start with a healthy group rather than one or two shrimp.
Can different Neocaridina colours mix?
They can live together, but crossbreeding often produces brown or wild-type offspring. Keep Blue Dreams alone if maintaining strong blue colour matters.
