Compatibility check
Can Betta and Zebra danio live together?
Betta and Zebra danio 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 | Betta is freshwater; Zebra danio is freshwater. Compatibility pages are generated only for matching water types. |
| Temperature | Caution | Temperature overlaps at 24-25 C. Betta is listed at 24-28 C; Zebra danio is listed at 18-25 C. |
| pH | OK | pH overlaps at 6.5-7.8. Betta is listed at 6.5-7.8; Zebra danio is listed at 6.5-8. |
| Hardness | OK | Hardness overlaps at 5-15 dGH. Betta is listed at 3-15 dGH; Zebra danio is listed at 5-20 dGH. |
| Adult size and predation | OK | Adult sizes are not an obvious predator-prey mismatch (Betta: 7 cm; Zebra danio: 5 cm). |
| Temperament and aggression | OK | Betta (territorial) and Zebra danio (peaceful active schooling) 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 | OK | Plan around full groups, not single display fish. Minimum group sizes: Zebra danio: 6+. |
| Explicit avoid tags | Conflict | Avoid-tag conflict found. Betta avoid tags matching Zebra danio: none. Zebra danio avoid tags matching Betta: slow-water. |
| Minimum combined tank size | OK | Use at least 20 US gallons (76 L) for the pair, based on the larger minimum tank plus bioload and activity adjustments where relevant. |
