Hello all, I have taken a hiatus of sorts from this site (fish are still alive and kicking...err, swimming), but I had a quick question. I noticed my male Betta has a little bit of a torn/discolored dorsal fin and was thinking a couple of doses of MelaFix could help this. You might think this is an odd question, but I wanted to ask before seriously messing up my cycle. Does anyone happen to know if tea tree oil will kill BB? I want to help my betta's fin heal, but if something like Stress Coat would be better, then I'll use that.
