Will I ever learn? Whenever i get a fish from petsmart, they never last more than a month. My poor little albino cory is dying. I never should've bought him, quite a few in the tank with him were yellowish. I picked him because he seemed lively and was very healthy looking, but small. Since I've had him, he hides a lot, and now it seems like he's always hiding, and not eating. I isolated him and and giving him medicated food, and he may be eating it, but I don't know if he'll make it. So sad. I need to find another source for fishies.
