fish are sick I was told by my LFS that Ich Attack can not only kill ich, but can also help internal problems with my angel fish. his poop has been white while he is refusing still to eat. ive tried live black worm, frozen blood worms and flakes. blood worms being his fav in past. so is this information valid? if not, what is in expensive that can help my angel and possibly others in the tank with the internal problems while im treating for minor case of ich again!
