When i bought him on Saturday, he had nice big purple lips and looked completely normal. He's spent much of his time hiding in/underneath the liverock in my tank. Tonight I noticed his lips are all messed up and has a white spot on his left side, and some maybe some whitish stuff on the lower part of his gills. Are his lips messed up from picking at algae on the LR, or is this something to be seriously concerned about. If it's a disease, I don't want it spreading to my other fish. I have no hospital tank to put him in for tonight (the 10 gal and smaller heater is still at my parents house). Any ideas?
