In Response To: Agressive Clown Loaches (BB)

From my observations of fish, they can and do learn behaviours. They don't appear to be hard wired in all aspects. For example, the easiest to discern is how a fish that has never seen a net will not swim away from it. Fish that have grown up in a tank and have never been netted are dead easy to catch. Then try doing it again some time. They never forget the trauma.

Right now I have an ancient female dwarf gourami who must be either senile or picked up her aggressive behaviour from a nasty blue gourami she was sharing quarters with for a couple of months. This fish gives the cichlids a run for their money.

Since the clown loaches that are picking on the pleco are sharing a tank with tiger barbs, is it possible that they've picked up on some barb-like behaviour? I have never seen my clowns bothering any other fish. On the contrary, they are intimidated by the Pearl gouramis who totally mind their own business. It seems to be a matter of size.
