One of my angelfish has red worms sticking out of it's vent. I have done research and i am certain it is callamanus. I called my vet and he has prescribed some Levamisole Hydrochloride. I would really appreciate some advice on 1. how to use it, and 2. the pros and cons of it. Also would be interested to hear with anyone who has dealt with callamanus, I have fry in the tank and am concerned for them.
