my black and white ocellaris are still chasing each other. it seems like the male is still not giving up. he is much smaller then the other one so im pretty sure hes the male. but its been going on for a month and a half. now he hides under my toadstool. but i just notice that it looks like theres some parts of his back and dorsal fin missing almost like the female is picking at him more aggressively. how much longer will this go on? and should i be extremely concerned to have to take the male or female out and put it in my little 5 gallon for a week or no? will this stop eventually?
