Aquarium center is the best in the area by a good margin. Hidden Reef is decent but as mentioned a little hit or miss. Their biggest problem is the people they hire though, they usually get some pretty cool stuff in. I've never been a fan of fish factory but they are great for getting live blackworms and they portions are quite nice. I've had nothing but bad experiences with them when it comes to buying fish. Those are really the only options unless you really want to take a drive. Captain Nemo's (actually now pets plus natural) is an interesting place to visit as they get some interesting stuff in, but the place is a dump and the prices are really high. There is also a pets plus in lawrenceville that gets in crazy stock by any standards (last time I went there he had like 5 different kinds of apistos and at least 3 other kinds of dwarf chichlids most of which I never seen in stores before) but the store is also a dump and while the guy in charge will brag about he can get anything, he has no clue how to actually keep anything healthy.
The options are fairly limited, but you should be able to find what you need between the few good stores.
