In Portsmouth NH -
Pet Quarters does have a decent selection, of the more common fish, they seem to know there stuff, a little bit, a tiny bit over priced when it comes to a few things though.
Little Shops of pets - always has a good selection of fish, I'd say litterally almost a full wall dedicated to them decent prices, seems to know quite a bit.
NERD/Zoo Creatures - a bit pricey, but generally has a decent selection of fish, decent selection of reptiles, however I have seen some crested geckos with stomaches that looked caved in, and a few dirty tanks.
