Fluid Dynamics International
Long Island Aquarium Store

It was an absolute pleasure talking to the friendly and knowledgeable staff at Fluid Dynamics. ...

Extremely knowledgeable and nice people. Excellent stock of fish and supplies. I’ve had a fish tank for almost 50 years and I’m looking to replace my tank. Brian couldn’t have been more helpful. He even took a working filter apart to demonstrate it’s features to me. They also offer custom tanks like on the tv shows. I highly recommend checking them out for aquarium needs.

It was an absolute pleasure talking to the friendly and knowledgeable staff at Fluid Dynamics.

I am a beginner and walked in with a rough idea of what I wanted and a million stupid questions. Jared was patient and accommodating. I went in for sand and some plants and ended up with what felt like a free consultation from an expert in the field.

The plants were all submerged and healthy (unlike many other stores) and all the tanks were clean and organized.

I will be a regular customer for sure.

The best customer service! I went in here looking for live plants and they walked me through 5 different tanks stocked up with options. I was also looking to add spider wood and a mystery snail - being a beginner their knowledge really helped create my finished product! They have great inventory and the fish are clean and healthy. Considering how friendly and welcoming the crew was, this will be my go to shop!

This is my idea of what an aquarium shop should be. Great variety of fish and beautiful aquatic plants. Staffed by people who are not only knowledgeable but care about the well-being of your aquariums and it’s inhabitants. I’ve been keeping aquariums for over 50 years and I’m impressed by their approach to helping people who want beautiful and nature-inspired aquariums.

Love all the fishes and plants... always stop by to visit the special kinds species u looking for!!😍😍😍

Fluid Dynamics is a top-notch aquarium shop with a very nice selection of aquatic plants and beautifully scaped display tanks that make plant shopping easy and inspiring. Their freshwater and saltwater fish selection is just as impressive, offering unique species you won’t always find at chain stores. The store is well-organized, the tanks are healthy, and the staff is knowledgeable. If you’re into aquascaping or looking for quality fish and plants, this place is a must-visit!

I got back into fish keeping after a 20+ year hiatus and going to the big box pet stores was quite a disappointment with dirty tanks and dead fish in most of them. Someone told me to try Fluid Dynamics, well this place has clean tanks and the fish are top notch. Jared the owner and his employees Brian and Cory are very knowledgeable and super friendly. If you’re looking for quality fish and learning about fish keeping this is the place to go.

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.
