when you buy those sick fish in those little cups you help support the store in buying and mistreating more fish. I agree that if you can get them to give you the fish free, then take the fish. Also if your plans are to breed, I would stay away from petco/petsmart/walmart like the plague. It is sad and complaining can get something done about it too. But coming in and buying them just makes room for more fish to sit and rot IMO.
Oh so sad. I was in Walmart today for other things and I saw to VT's just wasting. I was like, I hope they stop selling fish here because this is wrong.
