the spot is right behind his gills he has had it for a few weeks now and is has not gotten bigger or smaller. there also might be a spot on his tail but im not sure on that one any one know what it is or how to get rid of it. some times he brushes the spot on other fish or the glass but not any rock. other then that he swims fine and eats like a pig. so as much info as you can give me would be great. i know its hard with out good pics but i need a better camra. its only on the one side also. it took me 1/2hr to get that pic. i put a line around the bad spot. he doses seem more aggresive, sometimes
