I have a 5inch flowerhorn for about 6 months doin fine. He spawned with my blackbelt and the next day I notice cottony spots on his head and some on the side of his body. The next day it got worse so I take him out treat him with coppersafe and some fungus treatment. 2 weeks later he's fine so I put him back in the tank and couple weeks later spawn again and the same thing happens! What the heck. Never heard or seen this before can anyone help me out here with whats going on? None of the other fish get have this. Anyone?
