Do you have a tank to put it in by itself. If you do than treat it with Melafix. Works good . If not than remove your carbon in your filter , if you use carbon and treat the tank it,s in. Treat for about seven days and than do a 50% w/c. Hopefully that works. If it don,t than shoot it. Let me know how you make out. Quote Link to comment Share on other sites More sharing options...
Willfishguy Posted December 8, 2007 Report Share Posted December 8, 2007 It's soar for sure, but what caused it I do not know. The black around the soar is usually a sign of new tissue growth on large charcins. Quote Link to comment Share on other sites More sharing options...

It did heal in time, I used about half dose of malafix for a couple days Quote Link to comment Share on other sites More sharing options...
