I think maybe.. I'm having trouble getting a picture.
I'll try to explain...
I have had the problem for about 6 months, off and on...
My two perculas are loosing their fins, due to either an infection or a preditor.
They appear to be ripped off, partially or fully... litterally overnight.
They start off like white then they get fleshy, and then they heal.
My problem is that my fish are running out of fins! its happing almost once every 2 weeks if not more.
I thought it might be a crab, but I've set about 3 traps and cought nothing but hermits... I really need help Iding the problem, and finding a cure. I love my little fish and I really would hate to see them die.
