It started out with a growth,or something, on his left eye and was quarentined ASAP.The growth shrunk and now he has these things along the dorsal fin ,around the gill area and left eye.They almost look like the grubs or worms found in some pan fish here in Wisconsin.He dosn't really act sick ,he eats and fins are not all folded in ,but these marks are ugly and i'd like to know how to treat them if possibly.Like i said they look like grubs or maybe zits/acne.Here are some pics to look at.Thank You for any advice/help.
