My blue dwarf gourami definately has an internal parasite
. Are there any treatments which do not break the cycle of the tank? I am already trying to get my tank back to normal after foolishly using Bactersheild to treat a swordtail with body fungus. That killed all my good bacteria. I have a 10 gal hospital tank but my swordtail with body fungus is in there right now. Should I put the gourami in there too and treat him separately or treat him in my main tank as I read parasites can spread? Thanks!
