About
Tucked away from the big shopping centers in Williamstown, New Jersey, J B Tropical Fish is a throwback to the classic neighborhood pet shop — the kind of place where the owner knows your name and the tanks are spotless. Walking through the door, you're greeted by warm, humid air (reviewers warn to dress for 81°F) and rows of well-maintained freshwater tanks stocked with healthy tropical fish, including some impressive tank busters and unique species you won't find at chain stores. The store carries live plants alongside its fish selection, and the tanks themselves serve as proof of concept — planted, uncrowded, and carefully maintained.
Beyond fish, J B stocks reptiles, arachnids, and a robust feeder section with crickets, dubia roaches, and rats at prices that draw customers from well outside the local area. One reviewer drives from Philadelphia specifically for their feeders. Owner Dave and staffer Keith are consistently praised for their depth of knowledge across both aquatic and reptilian care.
Multiple reviewers note their patience in answering questions, offering tank tips, and helping newcomers make smart choices. One parent described how the staff spent genuine time with their son, walking him through different fish in the tank and explaining what made each one special. The store also handles custom builds for terrariums and captivities on display.
Pricing is a strong draw — reviewers repeatedly note that J B undercuts franchise pet stores while delivering healthier animals and better advice. The shop will even order specific animals on request; one customer had snails ordered on Saturday and picked them up by Tuesday. Used tanks are occasionally available for those building setups on a budget.
J B Tropical Fish carries the spirit of a 1990s local pet shop with real expertise behind the counter. For South Jersey fish and reptile keepers, it's a reliable destination with personality, fair prices, and animals that arrive home healthy and stay that way.

Customer reviews
“Best Fish shop in South Jersey! All my fish survive from here lol. For those aquarium enthusiasts, you know what I mean if I say there’s places that you buy a fish and they turn out dead or you notice nip tails and fins. I have a community of fish and JB helps add fishes that are hard to find. Top best places for me!”
