So my fish has this stuff that looks like cobwebs all over him, and it's clumping his fins so he can't swim and he's not really eating either. At first I wasn't too worried, since he had a 'beard' of this stuff shortly after I got him. Then, a few days away, I noticed a ring on one of his sticky fins (that's the name, right?) and today I found it all over him.
I don't think it's algae, since it's not in the tank and it's not green. It looks like cobwebs - clear and invisible until you get the right angle, and you can see hints of silvery-gray giving it a shape.
Any ideas??? I dunno if I can get a pick, since he's in a tight spot at the bottom of the tank, mostly.
