Amazing place amazing atmosphere come check them out

Awesome prices services and variety.

Clean and professional local fish store with friendly and knowledgeable staff

I had such a great experience working with this team for my aquarium setup. I’m on Long Island and was looking for someone who really knew what they were doing with custom aquariums, and they totally delivered.
They helped design and build exactly what I had in mind, and it honestly came out even better than I expected. The tank looks amazing and really changed the whole vibe of the room. You can tell they care about the details and actually know their stuff when it comes to fish and maintenance.
I also use them for regular aquarium service now, and they’re always on time and super easy to work with. If you’re on Long Island and thinking about a custom aquarium or need reliable aquarium maintenance, I’d definitely recommend them.

Had a great experience at Fluid Dynamics Aquarium Services and Store in Deer Park.

The owner Jared and Johnathan are truly amazing—kind, professional, and genuinely caring. Their positive attitude and good-hearted approach make this place stand out.

Johnathan is an outstanding employee—kind, respectful, and genuinely caring. As someone who knows him personally through my daughter Aaliya and my son Alif, it was great to see his professionalism in action.

Highly recommend!

I walked in not knowing what to expect. Was it an aquarium service store or did they sell fish? It turns out they do both. They had a very nice assortment of salt and fresh water fish. I was looking for discus and the employee who was also named John was very helpful. He said they would be getting discus in the summer. He pointed out some apistos that were very nice. He explained to me how to tell the male from the female and also not to put two males together. I strongly recommend anyone interested in fish to check this place out.

Amazing help with some new great fish. Will be back soon!

I haven’t been there in quite a while and it very refreshing. They remembered me and the store is gorgeous. Spotless, and it is growing. Filled with the most amazing fish!! How lucky 🍀 we are to have a real local Fish store like this …. It’s got great stock; great advice … open till 7 on Saturday… this is a Winning 🥇 place and I am glad to be able to come here. Btw the prices are insane … good! Huge Frontosas for less than $100 ! Love this place
