We have a small store in Rosenberg, small selection of sw fish, but if you want cichlids, they have them. The owner was showing me a couple he was very proud of, a new discovery, they don't even have a scientific name yet.
Other than that, all the stores are in Houston. Not sure how familiar you are with them, but here's some info in case you're not --
I like T&T's, especially for corals. IMO they're one of the top two fish stores in SW Houston, the second being Fish Gallery. If you haven't visited it, I highly recommend doing so. Small selection of sw fish, great selection of corals, and great selection of fw fish. I also like to visit Aquarium World (more NW Houston), with their 40,000 gallon sw display tank (with its 2000 gallon live rock "sump")... Another small store, but with a decent selection of sw fish is Fish Land. Next on my list of preferences is the small store Fish Ranch, and last is City Pets. I'd be careful about City Pets, though, anytime I've visited them I've seen animals getting substandard care.
Anyway, hope this helps...sorry if you already know all of that...
