This is the store closest to my house, so I go there quite frequently. I do have the feeling the owner (Bob) doesn't care as much as maybe he used to. And I have on several occasions sen dead fish in tanks, and the tanks need some serious love and cleaning. But I don't think it is as dirty as some other posts have suggested.
The variety of livestock is not great at all. Many types of tetras (neon, rummynose, glolight, beunes ares, etc etc), as well as platties, mollies, gouramis, swordtails, tiger barbs. And a few other fishies. Mostly fairly common fair.
However, he does have a large variety of Discus and Angelfish. And I have the feeling the health of those tanks is much better than the more common stock, as I have never noticed and fish looking poorly in those tanks. So if you are after Angels or Discus, it is a good choice. For more common fish, you may be better off elsewhere. But I purchased some neon tetras and 7 or 8 survived, which is pretty good.
For hardware and dry goods, not a fantastic selection, but again all the basics are there, and the prices are quite good. He also carries some knock of cheap Chinese brands, which are very cheap, if you want to save some money that way.
So, maybe caution in buying common fish, but OK for supplies and chiclids.
EDIT: Was in today (Jan 26/13), and he had the biggest variety I have seen in there. Corys, kuhli and clown loaches, rainbowfish, lots of new stuff. It was good to see the store so well stocked.
