Hello all, couple of days ago i've been seeing a couple of my fish with this but didn't really put much attention to it until i think my clown goby died of it. Can anyone tell me what is this white stuff on my clown? Does not look like normal ich.is there anyway to treat it? I don't wanna loose my clown he was my first fish on my tank and he is the only one showing signs of it,my other fish seem normal.
