Compatibility brief
Can Amano Shrimp live with Pea Puffer?
Risky. This mix is commonly discouraged for typical setups.
Amano Shrimp + Pea Puffer: Known incompatible pairing. Pea puffers are micropredators toward shrimp, do not mix in a standard community plan. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.
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).
Temperament gap (peaceful vs semi-aggressive) — can work with space, structure, and careful observation, but not a “drop and forget” mix.
Assessment details
Known incompatible pairing
Top issuePea puffers are micropredators toward shrimp, do not mix in a standard community plan.
Temperament difference
Pea Puffer is semi-aggressive, while Amano Shrimp is peaceful. This can work with adequate space and hiding spots, but monitor for bullying.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Amano Shrimp can escape if harassed.
- •Pea Puffer should be kept in a group of at least 6 for best health and behaviour.

Plan further
Try both species in the full-stock tank check, or open either fish profile for mates lists. 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 (Amano Shrimp): Based on typical aquarium care sources; trade names can be ambiguous, so details may vary between setups.
