Can Guppy and Tiger barb live together?

Guppy and Tiger barb 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 Guppy is freshwater; Tiger barb is freshwater. Compatibility pages are generated only for matching water types.
Temperature OK Temperature overlaps at 22-27 C. Guppy is listed at 22-28 C; Tiger barb is listed at 22-27 C.
pH OK pH overlaps at 7-7.8. Guppy is listed at 7-8.2; Tiger barb is listed at 6-7.8.
Hardness OK Hardness overlaps at 8-15 dGH. Guppy is listed at 8-25 dGH; Tiger barb is listed at 4-15 dGH.
Adult size and predation OK Adult sizes are not an obvious predator-prey mismatch (Guppy: 6 cm; Tiger barb: 7 cm).
Temperament and aggression OK Guppy (peaceful livebearer) and Tiger barb (semi-aggressive 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 Caution Plan around full groups, not single display fish. Minimum group sizes: Guppy: 3+; Tiger barb: 8+.
Explicit avoid tags Conflict Avoid-tag conflict found. Guppy avoid tags matching Tiger barb: fin-nipper. Tiger barb avoid tags matching Guppy: long-finned, flashy-long-finned.
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.
