So here's the background story
An acquaintance of mine, and her family was moving, and could not take their fish. So she offered them to me. As far as I know, they had been keeping two angelfish, a swordtail, and a bronze cory in a 5 gallon tank. So I immediately said yes, and arranged my other fish so I could take them in. They brought the tank to me on Saturday (9/1/12)
Now the angels, swordtail, and bronze cory are in my 29 gallon with lots of plants, two filters, other cories, a bn pleco, and zebra danios (the danios, i'm considering giving to the the pet shop for several reasons). I didn't notice if it was there the first couple of days, but last night I noticed what looked like some fuzz on one of the angels' lips. It might not be fuzzy exactly, but it looks off.
I can't seem to get a good picture, because this particular angel has a tendency to shy away from the camera. I was thinking maybe it could be either some sort of fungus, or slime coat weirdness? I don't think their tank had been cleaned very often...not sure how the angels looked so nice, and so big!
