Can Ember tetra and Molly live together?

Ember tetra and Molly are not recommended together based on the current rule check.

not recommended

Quick answer

This pairing is not recommended by the current rules. The highest-risk factors are marked as fail below; fixable water-parameter overlap alone does not cancel out predation, aggression, fin-nipping, or explicit avoid-tag conflicts.

Factor breakdown

Factor Result Explanation
Water type OK Ember tetra is freshwater; Molly is freshwater. Compatibility pages are generated only for matching water types.
Temperature OK Temperature overlaps at 24-28 C. Ember tetra is listed at 23-28 C; Molly is listed at 24-28 C.
pH OK pH overlaps at 7.2-7.5. Ember tetra is listed at 5.5-7.5; Molly is listed at 7.2-8.5.
Hardness Caution Hardness overlaps at 12-12 dGH. Ember tetra is listed at 1-12 dGH; Molly is listed at 12-30 dGH.
Adult size and predation Caution Adult size differs substantially (Ember tetra: 2.5 cm; Molly: 10 cm). Add cover and avoid housing juveniles with adults.
Temperament and aggression OK Ember tetra (peaceful nano schooling) and Molly (peaceful livebearer) do not have an obvious aggression clash in the dataset.
Fin nipping risk OK The dataset does not flag this pair as a fin-nipper plus long-finned combination.
Schooling and group needs Caution Plan around full groups, not single display fish. Minimum group sizes: Ember tetra: 8+; Molly: 3+.
Explicit avoid tags Conflict Avoid-tag conflict found. Ember tetra avoid tags matching Molly: none. Molly avoid tags matching Ember tetra: timid-nano-fish.
Minimum combined tank size OK Use at least 30 US gallons (114 L) for the pair, based on the larger minimum tank plus bioload and activity adjustments where relevant.
