Oh I was just at pet....bigboxstore yesterday they had little itty bitty sens maybe 8-10 a few albino all covered in what appeared to be ich. As did the fish in the "tank" next to it, I think those were tetras. I've heard people say polys don't usually get ich but I think they can and do.So yeah id treat as it was ich and if its not and some other parasite it my help that too. there is a sticky on poly meds I believe.
