I haven't seen any ada tanks around where I live, Montgomery County. Congressional aquarium sells good plants for a good price but their fish are really expensive. They also sell used tanks for a very cheap price. Another store is tropical lagoon. They sell their fish for a good price. Some of their fish are even cheaper then petco. Theres also other good stores in Maryland that I haven't been to. Other then that, you could go to petsmart and petco but I don't think they take good care of their fish.
