Compatibility brief
Can Cherry Shrimp live with Pea Puffer?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: low
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
40L
Combined minimum footprint reference for these two species: about 40L (larger active fish often want more length).
Pea puffers are obligate hunters of small invertebrates. Cherry shrimp look like food, not neighbours, including adults once the puffer is hungry enough. Heavy cover delays the outcome; it does not change the diet. Keepers who want both usually end up with a puffer tank and a separate shrimp colony.
Assessment details
Known incompatible pairing
Top issuePea puffers are obligate micropredators and shrimp are a primary natural prey item. A cherry colony lasts days to a couple of weeks.
Pea Puffer eats dwarf shrimp
Pea Puffer hunts adult dwarf shrimp the size of Cherry Shrimp. A colony becomes live food; survivors hide permanently.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

Next steps
Concrete changes, not "research more" filler.
- •Keep pea puffers with pest snails they are meant to hunt, not with ornamental shrimp. Give cherry shrimp a peaceful planted tank without small predators.
- •Cherry Shrimp should be kept in a group of at least 10 for best health and behaviour.
- •Pea Puffer should be kept in a group of at least 6 for best health and behaviour.

Plan further
Check each species’ mates list, size the glass, then verify the full stock in the builder. Methodology explains how verdicts are produced.
Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
Profile data confidence: medium. Driven by the lower-confidence profile (Cherry Shrimp): Typical care sources — real tanks still vary.
