About
Walk into Advanced Marine Aquatics in Albertson, New York, and you'll find Andrew — owner, hobbyist, and the kind of reef enthusiast who keeps a prized tang in his main display tank for close to 15 years. That single detail tells you everything about the care level here. This is a saltwater-focused shop where the coral selection is the main draw: zoas, torches, blastos, and an ever-rotating lineup of frags that customers consistently note are larger and more generously sized than what competing Long Island stores offer at similar or higher prices.
The fish selection runs deep on the marine side — firefish, sapphire damselfish, tangs, and cleaner shrimp are among the livestock reviewers mention taking home healthy and thriving. Andrew also stocks freshwater fish, which has surprised and delighted more than a few customers who came in expecting a saltwater-only operation. One reviewer even found help for a struggling betta tank, walking out with free filter media and rocks to get nitrite and nitrate levels under control.
What sets Advanced Marine Aquatics apart from the big-box alternatives and even other specialty shops on Long Island is the consultation that comes with every visit. Andrew routinely walks customers through water parameters, alkalinity management, lighting setups, and coral-fish compatibility before letting anyone leave with livestock. He's known for steering beginners toward soft corals as a starting point and being upfront about what will and won't work in a given tank.
Multiple reviewers drive from Brooklyn and Queens specifically for his advice and the confidence that comes with it. The store itself is compact — this isn't a warehouse-style operation — and prices aren't always labeled on tanks, so don't hesitate to ask. Maintenance services are available for those who need ongoing support.
The atmosphere is relaxed, the livestock is well-kept, and the reef knowledge runs deep. For saltwater hobbyists across Long Island and the greater New York area, this is a shop built on genuine passion for marine life rather than volume sales.

Customer reviews
“Wide variety of corals. And for some reason the $25 frags are always bigger than the $30 ones at Westbury reef supply.”
— Joshua Sukhdeo5.04 months ago“This business is a gem and the type of establishment that saltwater aquarium enthusiasts dream about. Andrew is a hobbyist first and with saltwater aquariums having a store that cheerfully and honestly guides customers through problems and helps them select livestock and corals that will work best for the customer. In his main display tank is a prized tang, a beloved pet he has owned for close to 15 years. That's pretty much all you need to know. Great service, fair prices, and whether you are new to aquariums or a hardcore enthusiast this is the place to go.”

— Barry Weiss5.06 months ago“The owner is absolutely lovely. I was having issues with my small betta tank bought from petco. He kindly gave me these special rocks and something for my filter to help get my nitrite and nitrate under control. He wouldn’t even charge me. Once my tank is back to normal I will absolutely be going back to add a snail or two to our aquarium. Thank you guys so much!”
— Kimberly ONeill5.07 months ago“Andrew is super knowledgeable and friendly”
— Rattanjit Kamboj5.08 months ago“Andrew was very helpful and knowledgeable. He has a good assortment of saltwater fish and freshwater fish! My neighbor was glad that he had freshwater fish. I started out with a simple saltwater tank. I had questions about which coral to start with. He recommended soft corals and I bought the one I liked. I love the green! I highly recommend his store. He’s very down to earth person. Thank you, Andrew for all of your assistance 🙏🏼”

— jason giannas5.010 months ago“Nice place”
— Guricancel4.010 months ago“I checked out this saltwater aquarium store, and let me tell you, it’s a straight-up paradise for us hobbyists. First off, their coral selection? Chef’s kiss. They had everything from zoas to torches, and the colors were poppin’ like crazy. I walked out with a sick blasto that’s already opening up nice in my tank. Their fish game is strong too—healthy, active, and no signs of ich or stress. I copped a firefish and a cleaner shrimp, and both are doing great. The Onwer? Super knowledgeable. They didn’t just sell me stuff; they actually gave me legit advice on my water parameters and lighting setup. Shoutout to the dude who explained how to dial in my alkalinity without crashing my tank. MVP right there.”
