Compatibility brief
Can Neon Tetra live with Tinfoil barb?
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.
500L
Combined minimum footprint reference for these two species: about 500L (larger active fish often want more length).
Tinfoil barb (about 35cm as an adult) can realistically eat Neon Tetra (about 4cm) once grown. Plan around adult sizes, not shop sizes.
Assessment details
Compatible temperaments
Both Neon Tetra and Tinfoil barb share a peaceful temperament.

Next steps
Concrete changes, not "research more" filler.
- •Neon Tetra should be kept in a group of at least 6 for best health and behaviour.
- •Tinfoil barb should be kept in a group of at least 5 for best health and behaviour.
- •Tinfoil barb reaches ~35cm: tank length and turning room matter more than the litre number. A tall, short tank of the same volume is not equivalent.

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.
