i have bought a few discus and put them in with my rays now the discus have little redish brown worms hanging out of the anus. i think they are Camellanus Worms.one of the discus has foggy eyes and the discus with a worm hanging out of the anus have very clear and white pop.now my concern is that thesw worms have spread into my rays.the rays are starting to slow down eating.what meds can i use to kill these worms once and for all.i forgot to mention that the one discus with foggy eyes also barely eats.pretty much doesnt eat at all.
