Compatibility brief
Can Chocolate gourami live with Tiger 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.
80L
Combined minimum footprint reference for these two species: about 80L (larger active fish often want more length).
Tiger Barb is a fin nipper and Chocolate gourami is vulnerable to nipping — long fins are a common target even when water parameters match.
Assessment details
Temperament difference
Top issueTiger Barb is semi-aggressive, while Chocolate gourami is peaceful. Expect chasing or stress unless the tank is large and heavily structured — monitor closely.
Fin nipping risk
Tiger Barb is a known fin nipper and Chocolate gourami has long, flowing fins. Tiger Barb will likely harass Chocolate gourami.
Narrow temperature overlap
Chocolate gourami and Tiger Barb have only a narrow shared temperature range. Maintaining stable water temperature will be important.
Narrow pH overlap
These fish can share water but their ideal pH ranges overlap only slightly. Aim to keep pH stable in the shared range.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Chocolate gourami can escape if harassed.
- •Avoid keeping Tiger Barb with long-finned fish like Chocolate gourami.
- •Chocolate gourami should be kept in a group of at least 4 for best health and behaviour.
- •Tiger Barb should be kept in a group of at least 8 for best health and behaviour.
Try instead
- →Swap tiger barbs for cherry barbs or harlequin rasboras if you want active colour without relentless nipping.
- →Build a species-only tank for the larger fish, or restock with fish too large to be eaten at adult sizes.

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.
