Fluid Dynamics International
Long Island Aquarium Store

Awesome fish store! Probably the best on the island. Their selection is great, the shop is beautiful and all the tanks are spotless. They have some of the highest quality fish I’ve seen and some of the most difficult to find sourced from Europe, where breeding practices are much more sustainable and healthy. Service is the best I’ve seen at any store (and I’ve been to a lot). These people are truly passionate about fish and know what they’re talking about, you can strike up a conversation with them and they’ll talk with you for ages about interesting information. You can tell that, unlike most other stores, these people are in it for the fun of the hobby rather than making a buck selling sub-par livestock.

Excellent store. The owner and staff are always happy to answer questions, share information, and chat about all things aquarium-related. The store has a great layout with a wonderful, well-stocked, healthy selection of aquatic plants and animals. The tanks are well maintained and pretty spacious, showing their commitment to the creatures they care for and sell. Always a pleasant experience when visiting/purchasing here.

Great attention from Corey. Very reasonable prices and great selection. Will be sure to stop by again soon.

I finally stopped in at Fluid Dynamics and was pleasantly surprised. All the tanks are spotless, the fish are healthy and they have a great variety of live plants! Jared was super helpful and gave me great advice on my planted tank.

Went here search around employees were very helpful and knowledgable, will be coming back and prices are very reasonable

Great customer service! Very knowledgeable and helpful! Will be coming back again!

Owner was great and very knowledgeable. They also had some really nice verity of fish.

Arguably the best fish store on Long Island. Stunning rainbowfish, clean tanks, and helpful folks.

I went there today and picked up a fish. Honestly the fish store is so aesthetic, I feel like I can just take a seat and just watch the tanks. Great quality fish and any question that I asked the owner, he provided me. He is extremely knowledgeable and can definitely steer you in the right direction. WILL DEFINITELY BE BACK!! Customer service 10/10 so great and I even asked if they were hiring 🤣
