Fish Gallery - Impressive facility, but more geared toward corporate setups and maintenance
City Pets - Large family run store. Best prices in town on dry goods. Have a decent supply of fish and corals (depending on when they get shipments, they see allot of traffic every week)
All About Fish - Smaller store, very clean with the best corals in town. Little more expensive
All are good in their own way. Usually if I'm looking for fish or dry goods I go to city pets. If wanting corals, I check out All About Fish. Unfortunately they are all spread out. City Pets is on the west side of town on the belt way, Fish Gallery is in downtown in the wealthy part of town by the Galleria, and All about fish is off of 45 and the belt way on the west side of town.
