I have had a mated pair of tank raised Ocelaris clowns for about 10 years. (They spawned once about 4 yrs ago but the fry didn't make it.) I moved them into a 15g Nanocube Deluxe about 1 year ago and everything has been fine... until last week. The larger female began beating up on her mate. She has become very territorial (especially at feeding). The male's fins are pretty damaged, he is losing color, he shows signs of distress and he now tries to stay "out of her way." My feeding routine has not changed, nor has anything else (to my knowledge). No new fish, now new life introductions to the tank. Any advice why this may be happening? What can I do to relieve the situation? Very odd. Does anyone suspect an changes in the female (doesn't appear to be carrying eggs).
Cheers,
Dennis
