Compatibility brief
Can Ember Tetra live with Golden Wonder Killifish?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: low
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).
Golden Wonder Killifish (about 10cm as an adult) can realistically eat Ember Tetra (about 2cm) 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

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Ember Tetra can escape if harassed.
- •Ember Tetra should be kept in a group of at least 8 for best health and behaviour.

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: medium. Driven by the lower-confidence profile (Golden Wonder Killifish): Typical care sources — real tanks still vary.
