This needs an update. If you are going for Cichlids you definitely go to the Fishhub, Allred cichlids, TropicalFishWholesale and if you really want some good tanganyika Cichlids at wholesale price you go to Bob Allen in Salem if you know anything about Tanganyika fish. If you don't know Bob then you're probably out of the loop.
The Fish Hub is awesome.
Animal Ark in Orem has an incredible plant and small fish selection.
Bob Allen in Salem has some hidden gems in his warehouse.
