Betta's in aquarium stores are not kept in individual aquariums due to aggression and water requirements. Betta's require very little water and live in the wild in very shallow patti fields.
I have been at Marine Warehouse at least 7 times with my husband and I dont recall seeing fishes in cups.That place is full of tanks.
Call them to confirm. Beta fish in seperate tanks are unusual because of the temperament of the fish.
