As of yesterday afternoon, I have one to add.
Mr. Aquarium on 34th and University in Lubbock is good. Their supplies are a little high-ish, but in line with LFS
prices vs. chain prices. Their fish are comparable price-wise and they have a good selection. Every tank was healthy and clean, no sick fish that I could see, though I didn't go into the marine section. The staff was really friendly and knowledgeable. They competently discussed fishless vs. live cycling and offered good input on future stocking plans that lines up with other information I had about the fish I was interested in.
