I've noticed a frayed dorsal fin on the angel I've had for 2 weeks. Sorry about the cruddy picture, but I think you can see what I'm talking about (maybe if you squint and look hard). S/he could have scraped it on my plastic plants or been nipped by the slightly larger angel in the tank (I've never seen any serious aggression, but the other angel is definitely dominant and occasionally gives chase and/or a little nip). I don't see any indication of fungus on the damaged fin. The angel is otherwise healthy... active, eating, etc. Water is good - ammonia and nitrites 0, nitrates 10, pH 8.2, temp. 79'. Besides the 2 angels, there are rummies, panda cories, and ottos in the tank.
I have Melafix but have never used it. Should I try it or just wait and see how things go? I'm loathe to start throwing things in the tank, but if it'll help the fin heal, I'll give it a go.
