Tucked into Bloomingdale, New Jersey, Aquariums By JJ is a family-run shop that punches well above its weight class in both freshwater and saltwater livestock. The store, which recently expanded a couple doors down from its original location, carries a surprisingly deep inventory for a mom-and-pop operation — reviewers have walked out with everything from zebra danios and tetras to flowerhorns, flounders, plecos, and batches of 30 goldfish. The saltwater side stocks a solid selection of marine fish along with anemones and clams, though coral hunters may want to call ahead.
What sets Aquariums By JJ apart is the hands-on guidance from the owner and staff. One first-time fishkeeper recounted how the owner talked them down from overstocking a new tank, effectively saving their fish from a nitrogen cycle disaster. Another customer got free moss tossed into their bag after a quick phone call about a specific fish.
The staff has a reputation for being straight with customers — they'll tell you when a shipment just arrived and advise you to wait, and they'll make sure a reptile buyer truly understands what they're signing up for before leaving with a new snake. The shop doubles as a reptile destination, with a dedicated reptile section next door featuring a wide selection of animals and hard-to-find supplies like specialty bulbs. The owner has been known to give kids personal tours, let them hold rare reptiles, and even show off "dinosaur eggs" — the kind of experience that turns a supply run into a family outing.
Tank cleanliness and fish health are frequently praised, with multiple reviewers noting immaculate displays and vibrant, strong livestock. The store also carries a solid range of aquarium equipment, parts, and supplies. A few visitors have noted occasional inconsistencies — one batch of tetras that didn't survive, or periods during the expansion when things looked chaotic — but the overwhelming consensus is that this is a passionate, knowledgeable shop where the fish come home healthy and the advice is genuine.

Really love this store and the staff is very knowledgeable. The guy on the reptile side isnt just trying to sell you a pet snd send you on your way, he really made sure I knew what I was getting into and even debunked some of the research I did and I was very thankful. We love our new snake and look forward to building a relationship with the staff like I do with most pet stores I frequent.

Extremely friendly local reptile and aquarium store. Called up looking for a specific fish, got a helpful answer on the phone and 10 minutes later had the fish in a bag. Got some free plants as part of the deal too -- just some moss he had extra but still. Very happy with our walk in. Cheers!

Just a really strange shop. Messy, cramped, and most of the tanks didn't even have any fish or other creatures in them.

Owner was nice, got 3 types of fish unfortunately the tetras all passed away the next day in tested water. So looks like 1 batch out of the 3 weren't good.

I went there after spending over an hour waiting for help at Petco and googled this aquarium place and off I went. My granddaughter got a fish tank for Christmas and I don't know the first things about what to do. Walked into his store and was greeted immediately and explained what I needed and he was more than happy to help. ( Even when I changed my mind numerous times) I will definitely be going back and sending my friends there. Thank you for all your help.

I took a long drive for another visit to this shop looking for some plecos and a few other aquarium items. The first time I stopped here I was pleasantly surprised with the health of the fish and the store in general. They were in the midst of expanding their shop two doors down, so things were understandably a little chaotic. Unfortunately this time I was kind of shocked by the conditions the fish were in. Lacking color, signs of bacterial/fungal issues—which shied me away from making any fish purchases. I saw some bettas that were in a cup on the counter and took a peek— ugh. Looking terrible and sad— one was kept in a small bowl, no heater or filtration. Very disappointing. Then I ventured to the new ‘reptile store’ they have opened. Lots of good supplies but sorry looking animals for sale. Staff wasn’t the friendliest, at least the guy behind the counter. He seemed miffed to stop what he was working on to help. Sorry, but I won’t be returning.
