Compatibility brief
Can Neon Tetra live with Senegal bichir?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: medium
How we decideFishori checks adult size and predation risk, behaviour, water requirements and tank needs before giving a verdict.
300L
Combined minimum footprint reference for these two species: about 300L (larger active fish often want more length).
Senegal bichir (about 35cm as an adult) can realistically eat Neon Tetra (about 4cm) once grown. Plan around adult sizes, not shop sizes.
Temperament gap (peaceful vs semi-aggressive) adds stress on top of the hard incompatibility — space and cover do not make this pairing safe.
Assessment details
Temperament difference
Senegal bichir is semi-aggressive, while Neon Tetra is peaceful. Expect chasing or stress unless the tank is large and heavily structured — monitor closely.
Senegal bichir may eat Neon Tetra
Top issueSenegal bichir (35cm) is predatory and Neon Tetra (4cm) is small enough to be eaten. This pairing is unsafe.
Narrow temperature overlap
Neon Tetra and Senegal bichir have only a narrow shared temperature range. Maintaining stable water temperature will be important.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Neon Tetra can escape if harassed.
- •Neon Tetra 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.
