I used to work at Aquarium World.
Yes, the prices are high, but I doubt you will find a more impressive store with experienced staff as a general statement.
FWIW, I happen to disagree with some of their opinions, but many of the staff have been there years. They also have a 7 day guarantee. I find discussions on these boards amusing. People want a lot in a store (clean store, knowledgeable staff, excellent warranty) but complain about prices. :notsure: Oh well. It is worth seeing regardless of whether you buy anything at all. They have a 40,000g display (so they say), a 3000g sump and some other large displays.
There are many other LFS in the area, many of which are sketchy but have lower prices. These include:
T&T on Hwy 6 south of the westpark tollway (perhaps one of the best)
City Pets on Beltway 8 and, uh, bellaire or bissonet or beechnut, I can never remember.
Global Fish and Pets is in the area, about 4 miles east of beltway 8 on again, bellaire or one of those B's (on a map it is the first major street south of Harwin).
FishLand on Westhiemer and Synott
AquaticWorld is in the Aquarium World neighborhood (gee, not trying to pick off the name) at 290 @ Jones.
Village Tropical has recently moved...but may be worth finding (though again nice store = expensive)
Or you can just go to the local reef club for directions as many are sponsors. Google Marshreef
Also consider the Aquarium Restaurant downtown which is an interesting place to eat (I also worked there
)
