I have had 2 true perculas for about 3 1/2 months now and when I bought them they were the only 2 clowns in the same tank. They are both very small and the first week I had them the larger one chased the smaller around and dominated it. Now the smaller one is starting to assert itself and has the larger one hiding in the corner. Can anyone explain this behavior?... I am assuming they are both still to young to sex yet ... maybe this is the start of the process.
