I have had my tiretrack eel for about 3 months. He has had this abscess or open wound for the last 1 month, and he seems to still be eating and growing just fine. His only tankmates are some clownloaches, a Raphel cat, and a pleco and we have never seems any aggression. We have been treating him with melafix for the past 3 weeks, and it doesnt seem to be changing at all. Here are some pics of what I'm talking about. Any thoughts or suggestions? Thanks.
