OK, here is an update on my fish, "Rolo." Four days ago, I started him on Tetra Parasite Guard (mixed into his tank water in the recommended dose). Along with the usual water conditioners (Tetra Aqua Safe Plus and Tetra Ammonia Safe), I added 1 tsp. per gallon of Epsom salt to his water. I slowly acclimated him to this new water, and he tolerated it quite well.
During this new course of treatment, he's been acting normally, and his appetite is fine, but now I am worried because he hasn't had any kind of bowel movement for four days! No fish feces, no worm feces, no worms, NOTHING! So he went from having 2-3 bowel movements and passing approximately a dozen worm feces per day, to not passing a single thing.
I know the epsom salt is supposed to help him expel the dead worms, but how long should that take? Should I bump up the dosage on the epsom salt to see if that helps him pass the worms and have a bowel movement? I fed him frozen daphnia tonight as I know it is a laxative, but should I continue feeding daphnia, or should I fast him for a day to give his system a rest? I know he needs nutrition to heal, but I am so afraid of causing bloat if he is all stopped up with dead worms!
