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 | Chili rasbora is freshwater; Swordtail is freshwater. Compatibility pages are generated only for matching water types. |
| Temperature | OK | Temperature overlaps at 23-28 C. Chili rasbora is listed at 23-28 C; Swordtail is listed at 22-28 C. |
| pH | OK | pH overlaps at 7-7. Chili rasbora is listed at 4.5-7; Swordtail is listed at 7-8.3. |
| Hardness | Conflict | Chili rasbora is listed at 1-8 dGH, while Swordtail is listed at 10-30 dGH; there is no shared target range. |
| Adult size and predation | Caution | Adult size differs substantially (Chili rasbora: 2 cm; Swordtail: 12 cm). Add cover and avoid housing juveniles with adults. |
| Temperament and aggression | Caution | Chili rasbora is described as peaceful nano schooling; Swordtail is described as peaceful to boisterous livebearer. Watch for bullying, especially in small or sparsely decorated tanks. |
| 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: Chili rasbora: 8+; Swordtail: 3+. |
| Explicit avoid tags | Conflict | Avoid-tag conflict found. Chili rasbora avoid tags matching Swordtail: boisterous. Swordtail avoid tags matching Chili rasbora: 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. |
