I've had a 32-gallon biocube with a single ocellaris clownfish for a year and a half. Two weeks ago I added a purple firefish and royal gramma to the tank and the clownfish had no issues with either. Suddenly a few days ago the clownfish started going out of its way to attack the new tank mates. It isn't just defending its territory it's deliberately going after the others. I believe the clownfish is in the process of becoming a female because it is looking much larger. Lately, I've been letting the clownfish sit in a net alone in isolation. I tried one day let him back then tried two days and just let it back in the tank. Each time I release the clownfish it is even more aggressive. I have just caught the clownfish for the third time and it is floating in the net. Should I leave it in for a week and is there any hope to reduce it's aggression?
