Might want to check out http://ctfishstores.com/site/ct-fish-store-map.html
It has a pretty thorough listing of stores. Most of the members are saltwater guys/gals and the LFS often update stock lists on corals etc. But, they do have some discounts and specials at a lot of the shops worth taking a look at.
Puppy Center is my primary shop for fish. Aquatic Wildlife in Manchester has a nice plant selection if you come near when the shipment arrives (just call and find out), although prices can be a bit high. Every once in a while exotic superpet in E. Hartford has some hidden gems from a fish perspective; as does Emmons in Simsbury.
