Compatibility brief
Can Amano Shrimp live with Pea Puffer?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: low
How we decideFishori checks adult size and predation risk, behaviour, water requirements and tank needs before giving a verdict.
40L
Combined minimum footprint reference for these two species: about 40L (larger active fish often want more length).
Adult Amano Shrimp usually survive alongside Pea Puffer, but small or moulting shrimp are at real risk. Dense cover matters.
Temperament gap (peaceful vs semi-aggressive) adds stress on top of the hard incompatibility — space and cover do not make this pairing safe.

Top issuePea puffers are micropredators toward shrimp, do not mix in a standard community plan.
Pea Puffer may pick at Amano Shrimp
Large adult Amano Shrimp usually survive Pea Puffer, but moulting or small individuals are at real risk. Dense cover is essential.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

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.
