I have a adult angel fish that has been laying on its side for several days. I have isolated it and been using micro lift anti bacterial plus their anti parasite remedies plus Tetra Medicine it will swim when disturbed but eventually just return to the bottom of the tank. I have also tried the Epsom salt remedy for it in a five gallon bucket. It is still hanging in there but I am out of options as to what is needed or what I can try next. It is now in a 20 gallon tank alone with filter and air stones
