I added a Clownfish to my tank a week ago and all seemed well, he was eating fine, but after a 2 days I noticed above his mouth just under his eye that it looked like he had a cut there it was redish but its now turned into a white/grey type fungus, atleast thats what I would describe it as, his body has become slight greenish in areas!he also seems to just stay in one corner of the tank as if hes just looking at his reflection all the time! PH is 8.2 No Amo or Nit levels PLEASE HELP! I cant take a pics at the moment coz my camera is broke,sorry
