I might recommend the following stores, sort of in the area.
Fish Man (in Denton - I always enjoy this store)
Dallas North Aquarium
Aquarium Trading Company
The Fish Gallery (great store)
Also, make sure to check out the DFW LFS page on our website before you go. All the stores I have listed are on that page.

Lastly, if you have the time, give me a ring when you are passing by Ardmore. Or, I'll be in Dallas (Irving) late tomorrow night if you are still around. I would love for you to come by either home in Ardmore or Irving. And my Irving apartment is open to visitors, if you need a place to crash for the night.
In Ardmore: 823 D Street NW
In Irving: 3515 Coker Street, Apt #218
Cell Phone: 580-277-9037
Have a great day, no matter what you see!!! Tell Scott @ Saltwater Paradise that I sent you by. He might give you a good deal for that. Also mention COMAS and thank them for supporting our club.
