Hello kkimjames! I'm also from NJ ( middlesex county). I just set up a 90 gal FOWLR
tank in October. Needless to say I've been to a "few" fish stores lately. My favorite spot is ocean gallery 2, it's on RT 22 in North Plainfield. I got set up there with everything, sump, skimmer, pumps, tank, stand, EVERYTHING. They have GREAT cultured live rock ( pricey but great rock) healthy fish and corals, good staff.
Tropiquaruim in ocean township is good, the pet shanty ( forget town, also on 22). Another decent spot is "absolute fish" in Clifton. Traffic is killer up there though!!
Let us know how you make out after you set one up
