I love my walmarts. One of them has a tank for females and the males are kept in those cups, but these ones are like 1/2 a gallon. Thats bigger than the bowls at the pro. lfs. They change them all the time and barley have dead ones. They alos remove the sick ones and ones with bad fins etc. and treat them for their problems. The ones I got there are great. The other one is usally out of bettas because they go so fast in that area. But once they did have four left and they were good. This one though does have some dead fish. But thats only on Sundays when they dont have people working there. The other one though has a hospital tank for other fish and treats them very well. Feed them and change the water. Walmart is one of the best places to buy fish. they also have a larger variety then most places. Actually all places that sell fish around me are very good, except for the place in the mall, but when I went there last time it wasa good and had a lot of diffrent and big fish.
