im truly bumbed, have had many batches of p, never have lost an eye, wierd part is i usually never took this good of care of them either. used to just throw a bunch in a tank and let them go. been feeding them feeder baby guppies and shrimp, along with flake and pellets that i feed the feeders. I called lfs, safari land in sioux falls, sd, they said they might have got a bad batch out of florida
