my Hujeta "gar" has this red bump on its side i have been treating for 7 days on melafix. but it is still there what is it if any one knows and by the way he eats aggressively and isnt even skittish. i walk up to the tank and he comes forward its a cool fish and i dont want to lose him. so whats wrong with him? sorry bout the bad pics but u can see the bump verry well
