Butterfly fish would be a
Very Poor choice of companion for Tiger Barbs. Butterflyfish are generally slow moving with long tapering fins . Tiger Barbs, especially a small group, are aggressive, fast fin nippers and will find it absolutely irresistible. Although BF fish rarely eat anything bigger than a
neon tetra, they will compete heavily for food at the surface with the Tiger barbs.
There will be definite losers on both sides. Butterfly fish can cope with a small tank with low surface movement and lots of floating plants.
