[edit] Behaviour

Peaceful, active and a good community fish. Will school in groups of 6 or more. Other fish use this fish as a spotter fish; that is, if there is a predator about these fish will spot it first. Therefore, other more timid fish will come out into the open more if you put these fish in your tank. Useful also to the aquarist as an indicator fish. If they are closely packed together, then they are alarmed and feel threatend. Usually if they are settled, they will disperse over your tank.
