Compatibility brief
Can Pea Puffer live with Senegal bichir?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
300L
Combined minimum footprint reference for these two species: about 300L (larger active fish often want more length).
Senegal bichir (35cm adult) may treat small Pea Puffer (~3cm) as food once grown — plan adult sizes, not shop sizes.
Pea Puffer is a fin nipper and Senegal bichir is vulnerable to nipping — long fins are a common target even when water parameters match.
Assessment details
Compatible temperaments
Both Pea Puffer and Senegal bichir share a semi-aggressive temperament.
Senegal bichir may eat Pea Puffer
Top issueSenegal bichir (35cm) is predatory and Pea Puffer (3cm) is small enough to be eaten. This pairing is unsafe.
Fin nipping risk
Pea Puffer is a known fin nipper and Senegal bichir has long, flowing fins. Pea Puffer will likely harass Senegal bichir.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

Next steps
Concrete changes, not "research more" filler.
- •Avoid keeping Pea Puffer with long-finned fish like Senegal bichir.
- •Pea Puffer should be kept in a group of at least 6 for best health and behaviour.
- •Senegal bichir reaches ~35cm: tank length and turning room matter more than the litre number. A tall, short tank of the same volume is not equivalent.
Try instead
- →Build a species-only tank for the larger fish, or restock with fish too large to be eaten at adult sizes.

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: high. Checked against several solid care sources that mostly agree.
