One of my Rosy barbs is now chasing the other 2 barbs regularly and sometimes the other types on the odd occasion. Their were all getting along fine when one day it started chasing the others, its also the smallest of the bunch. Remove him or is it a phase ?

Thanks!

The thing with barbs is that usually the more you have, the better they get along since they are shoaling fish. With 2 or 3, you often get chasing and fin nipping.

You should have at least 5 or 6 to avoid aggression, but your tank is a bit too small for that with the other fish you have in there.
