My mom was looking at the 1/2 gals and I wound up asking her how she'd feel living in a closet. She thought they were cute and asked me "why would they sell it if it wasn't okay for them to live in". Those super small tanks shouldn't exist. Anyway, I'd make a complaint with Walmart but I feel it will go nowhere. If I ever decide to venture into that part of Walmart again and find more dead boys :( I will give their manager an earful. No animal should be subjected to such conditions. Fish are such amazing creatures its a shame not alot of people see that. It's one of the reasons I signed up to these forums.
