Rubbernose pleco, fungus?
I have a little rubbernose pleco in my tank (his brother long dead) and he has developed a white-ish condition beginning just behind his eyes and stopping before the dorsal fin. The problem is that, should it be fungus, I have two clown loaches (sensative to chemicals/meds) and the tank is planted. I do have a suspicion that it may be a scratch because I have recently changed the tank. The fish is otherwise happy, darting around the aquarium like nothings wrong and no one else shows any symptoms of fungus. So, is it worth medicating or removing the fish or should I just let them be?
