Pretty much the same in Arizona. All cats & dogs are adoptions from various rescues, and have a history of each individual animal as well as the name of the rescue organization. Both sell birds, fish, a few reptiles, rats, mice, gerbils and hamsters. Cages are always clean. I know a few people who have worked at PetSmart, and they are very particular about both customer service and animal care.
If the fish were being permanently housed, larger tanks might make sense, but they are for sale, and expected to be sold in a relatively short timeframe. Keeping them in large tanks with a low density of fish makes no sense. Ditto for the betas. Most are male, and it put in tanks together will fight and kill each other. In the wild, betas do not live in a large area--they maintain a very small territory.
