Compatibility brief
Can Ember Tetra live with Green Terror?
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).
Green Terror (about 30cm as an adult) can realistically eat Ember Tetra (about 2cm) once grown. Plan around adult sizes, not shop sizes.
Ember Tetra (peaceful) and Green Terror (aggressive) are far apart on aggression — bullying or injury is a common outcome in average community layouts.
Assessment details
Aggression mismatch
Top issueGreen Terror is aggressive, while Ember Tetra is peaceful. The aggressive fish will likely bully or harm the peaceful one.
Green Terror may eat Ember Tetra
Green Terror (30cm) is predatory and Ember Tetra (2cm) is small enough to be eaten. This pairing is unsafe.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

Next steps
Concrete changes, not "research more" filler.
- •Ember Tetra should be kept in a group of at least 8 for best health and behaviour.
- •Green Terror reaches ~30cm: 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.
