Unknown spot on clownfish...HELP!

Does anyone know what this spot on the whiteband behind the eyes of my clownfish is? It showed up last night and has grown slightly. The fish did not eat today when I fed the tank and is swimming eratically.

keep an eye on him.. id say.. can really see what it is.. if you notice anymore, pull him out and put in quarintine.. in the meantime i know you said you were feeding him frozen brine shrimp.. try mixing it up and giving him flakes and pellets. also soak the food in garlic (kent garlic or buy cloves and smash it up and get as much juice from that as you can) garlic is supposed to help there immune system.

I believe brooklynella causes fish's skin do that. As it's a clownfish, that raises the chances of it being brooklynella significantly. Formalin dips are the recommended treatment for brook I believe. If it is brook, hypo or copper will not work.
