Yes, he is rubing against the coral and the spots are very small, slimy looking I guess you could say. No other fish seem to have the same problem. I just introduced the inverts package of crabs,shrimp and snails 2 weeks ago.
Help!! One of my trigger fish has got white spots on the sides of his body. What is it? And what do I need to do to cure it? Thanks for the help!!
