Route 4 closed and moved down the road. Sorry to say the new store is not worth stopping at. I was there 3 weeks ago, what little fish they had were in sad shape.
The Pet Shanty is closed up and gone.
Shark Aquarium, Aquascape "Aquarium Paradise", Absolutely Fish, Adams Pet Safari, The Fish Hut, Sea Level Aquarium are the North Jersey stores I go to. If your into NY there's Monster Aquarium in Flushing, I've never been there but they post nice fish on their Facebook.
Central Jersey, Tropiquarium, Sharkeys Aquarium, RT 88 Pet world, Jenison's Aquarium not a LFS but small Commercial aquarium worth checking out if in the area.
South Jersey, Aquarium Center, Ocean Aquarium, JR Aquarium, Monster Pets. There's the Camden Aquarium large commercial aquarium not a LFS worth the trip from anywhere. It will take you about 3 hours to go through. There are several large fresh water displays along with an Amazon display with a large Arapaima.
Not far from South Jersey in PA is The Fish Factory, The Hidden Reef, and another Monster Pets in south Philly.
I could go on..........LOL
