I'm from J-town too! Nice to see some people from AR on here.
Kinda sucks cause Best Pets and Tropical Paradise are both closed now.
I either got to memphis or Tropical Adventure now. Also in Memphis there is a fairly new store called Mempfish that's good, and for pond and reef livestock and supplies, check out Something Fishy. As for Petco, the one here is descent, just don't ask the employees for info.
Also, Oqsy, if you don't mind me asking, where did you find color quartz around here?
