Siamese Fighting Fish and Sumatran Barb: can they live together?

Verdict:not recommended

  • Behaviour: not recommended
  • Water: ranges overlap

Why

The Sumatran barb nips long fins, and the Siamese fighting fish has exactly such fins. This neighbour is dangerous for the Siamese fighting fish, so keeping these two fish together in one tank is not recommended.

This is a general estimate: fish of the same species differ in character. Tank volume is given for each species separately — two species together need at least the larger of the two, and usually more.
