When I got home from work today, I noticed this issue with my clownfish. She’s the only
Clown in the tank. Her tank mates are a Midas blenny, clown goby, blue chromis. No fish have been introduced into the tank in nine months. This seems to have happened over night. Any help would be appreciated.
Could be a case of fin rot, but I'm in no way a disease guy, so please wait for others to respond. I'm moving this over to the fish disease forum for a better look.
