I have about an 8 in tire track eel. Ive had him for about two months and been feeding him earthworms, krill, and bloodworms. He was doing fine until i noticed a white lump in his side about two days ago. Now it has opened and looks like something is sticking out of it (really nasty), but the is also a lump on the opposite which makes it look like something is stuck there. Does any one have any advice as to what this might be or what i should do. He's in a 38g tank with a smaller fire eel, a larger cichlid, and two plecos. No other fish are showing symptoms of anything unusual.
