I go up the toll road to Dallas North Aquarium (more frequently than I should admit) as they've got one of the largest dry good selections in the area. They also have some live foods if ever you have picky eaters. They don't seem to advertise their live foods very well, but you can ask someone in the store (or call - its how I found black worms local... after I already ordered California black worms from Pennsylvania distributor (DUH!))
If you have corals, get good on your QT/dip procedures because ALL our local fish stores seem to have one thing or another going on at any given time no matter how hard they try to clear up and/or control whatever... and a few little LFSs I've run across don't even try to keep it controlled.
BRS has great dip video; I'm expanding my dip process for all three types of dip (hydrogen peroxide, an iodine based, a natural based) and need to get Bayer for 4th type (insecticide) which isn't in BRS video just so I'm sure to keep my tank clean now that I've gotten it cleaned up of worms and nuisance algae (aiptasia is around too, but I've gotten lucky there - just 1 so tossed plug and rock where it was found. Got Frank's F-Aiptasia (he's Fort Worth based, small but AWESOME people & known for special ordering anything) but the product has gone international so likely easier to just mailorder than drive over there (but you can see the original non-family friendly F-Aiptasia product label if you ever go into store and know where to look <wink>)).
