I just bought a pleco yesterday ago from my lfs and he was fine and active for the entire day but later that night he stopped moving, and stayed in one spot. this morning he was still in the same spot and his fins were a little torn up. About an hour ago I looked and he had a few irregular whiteish spots on him but there were only a few. I have a 55 gallon tank, hard water, ph-6.8, I use quickdip test strips, ammonia is ok, nitrates and nitrites are in check, its freshwater, aquarium has been set up for about 2 months, i ahve a 6 inch senegal bichir, a 3 inch bala shark, 3 inch pictus cat, 6 inch needlenose gar, 2 red claw crabs, brown knife fish, and a giant danio. (besides pleco). Fish was not placed under quarantine (still trying to get a tank for one) temp is 78, no live plants, emp 280 filter, no sunlight, last water change was today i did a 50%, fish get fed shrimp pellets/ occasional rosy minnows.
