We have an adult Tangerine Peacock I noticed hanging out in the corner at the surface this morning, not eating as well. After closer inspection, I see what appears to be some kind of fungus? on its gill plates. It looks like white pealing skin. I moved to a 5.5 quarantine tank and treated with Melafix. My questions are, what is it and what treatments are necessary to heal it. And is it contagious? I carefully inspected all tank mates finding no signs. Also, I highly doubt it was caused by another fish, its a pretty low aggression tank.
Thanks!

Thanks!
