Hello everyone. I purchased a new pair of palatinum clowns. I got them and it seems like one side of one of the clowns face where his gills are seems to be swollen of extended farther off of his face. I did some research and it could possible be a parasite. I treated the water with a antibacterial water additive. I did the treatment for 7 days and then i did a 25% water change. the fish seems to be breathing better but he still kind of breathes heavier when he's not really doing anything. do you all think that he will recover from this? His appetite is great. Activity is great. He swims like nothing is bothering him.
