There's Sea Critter's Depot. Bruce owns that store, but it's saltwater only. There's also a place called Wet Pets and More (fresh and saltwater). I know nothing about this store. Maybe someone else on CFT can chime in with suggestions?
Wet Pets -This was a cichlid exclusive store at one time but their website now says they also have saltwater. Small store but when I visited (when it was cichlid only) they had a good selection. (Near Robert Grissom Parkway & 38th Ave N.) 3541 Fountain Lane www.wetpetsandmore.net
