I have noticed in the past that there are quite a few tropical fish keepers on here. Has anyone come across the below:
It has only developed on one fish so far, doesn't appear to be affecting his desire to eat, and he appears to be unaffected by it. It seems unlikely it is white spot as the patches are too large and my Clown Loach (usually the first to contract white spot due to having no scales) are unaffected.
Any ideas?
I am going to go up to the fish shop tomorrow morning to see what treatment I can get.
