If only there were an option for 0 stars I would give them 0 stars. When I first went I thought wow what a great store - so many options multiple rooms. Until I spoke to the staff. They are rude and seems uninterested in talking at all. I figured whatever - they have a great selection - I will still get it from them. Then the fish I got came with Ick (A parasite that kills your fish!) within a day or two after bringing home Albino Cherry Barbs. They developed white spots all over. I am new to the hobby so I thought it had some glistening to the the tail fin of the fish. I did not know yet to quarantine new fish in a separate tank for two weeks before introducing them to your tank, so now my entire tank could be infected. I did everything I possibly could to keep them alive - Ick treatments, increase oxygen, etc. But sadly two of them died. It cost me money to buy the fish and even more to desperately try to treat /save them. Now, all my fish are at risk and the only treatment I could get in time also may kill the aquatic plants we have - ultimately ruining my entire tank! Which I also bought from their store. Insanely, they sold aquatic plants that are known to not survive in the tank. My plants started to develop what looked white hairs or roots growing from the side. And i found out Aquariums stores sometimes sell this plant knowing its not an aquatic plant but can last months before dying. I took them out and replanted them in a pot. Hopefully they don't die too. So beware not just of the fish but the plants too! After calling the store - the guy blamed me at first for the fish getting sick. He said he "doesnt sell sick fish" yet all my original fish were fine - just these new fish within a day after bringing them home developed Ick. I told him are you crazy - how could I have done it? He then proceeded to call me crazy!!! And told me said they do not guarantee live fish! He kept insisting I was wrong until I said Albino Cherry Barb - he went quiet. Then offered me the only two fish he had left. Clearly it was a known issue. Keep in mind a week before he had at least 30-40 of them in the tank. When we were there 3 albino barbs were left less than a few days later and they did not replace them. Hmm - I wonder why? I am not going to take those fish either because they are probably sick too and he told me no refunds. Will never shop here again. Be careful guys!

Gar is happy!

Amazing got my order and everything was alive and healthy looking. VERY PLEASED and ordering again this week! Suggesting to all my friends and even strangers and definitely ordering again this week!..

Turtles so small and crowded
Sara H.

I had a truly disheartening experience at this aquarium supply store. While they did have exotic fish, their living conditions were appalling. The tanks had barely enough water, and the turtles were crammed into a small space. I witnessed one turtle cannibalizing another, which was both sad and horrifying. Many of the turtles seemed too small to be sold. I'm going to contact the proper authorities about this, and there were even free-roaming cats in the store to control the obvious mice issue in the bottom aquarium room. I'm giving this review 3 stars only because lower ratings seem to be hidden, and I want everyone to see this and the pictures.

Our fish is dying

See all

How long does fish last if bought and bagged in plastic?

Bags aren't designed to keep fish in them long term, but that being said, shops do ship fish and inverts in bags, and shipping can sometimes take a few days. Just make sure that there is enough air (you need enough air to oxygenate the water) and… Read more

Cory and Downs have been around forever. I have been dealing with them since the Suffolk County…read moreFish & Reef days. That's when my addiction started. I remember being fascinated by the plumbing setup in that store. There was basically a network of plumbing under your feet. I think the new store is by appointment only and I've been there a few times. It's worth the phone call and personal attention. Call to confirm this though, I am not 100% sure. I consider myself well-versed in the hobby but that doesn't mean I don't need a hand from time-to-time and it certainly doesn't mean I know everything. Some of my coral wasn't looking so good and I just wanted someone to take a look and offer their opinion. Downs did just that. I called Downs at noon on a Friday and they were booked for the day but he still stopped by at the end of the day to help out. I figured I wouldn't see anyone for at least a few days, never mind same-day. He was concerned that if we waited to long I might lose a few pieces and he didn't want that to happen. Downs is a really good guy. Doesn't try to shove products down your throat or his methods. This hobby definitely isn't a one-size-fits-all and he understands that. While I don't think he agreed with all of my methods, he considers them and works around them. While I enjoy doing my own water-changes and maintaining my own tank, I will definitely have Downs by once a month just to look things over. One other important thing to mention and this may or may not be important to most people. With babies and kids in the house, we take our shoes off. As soon as Downs walked in, he took his shoes off before I even had to ask. Now imagine having them service your tank(s)? Drop-clothes, plastic, I am sure they are meticulous. I'll see you soon Downs, thanks again!

Thank you Total Aquariums! They got my fish tank set up and before Christmas! My husband loved it…read more Also they take care with giving advice on what fish to get and decoration options. I found the service exceptional and I highly recommend them.

This was my place to go frequently for all my fish and supplies when we lived in the area…read more Extremely knowledgeable and professional staff. They definitely know their fish - from breeds to care to what and how much to get to decorate your tank. Expert advice on what type of fish may suit your needs and will actually go out of their way to explain why. They actually care that you will take good care of these little guys. For a reasonable fee, you can have them come to your home to set your entire tank up. This was the TOPPER that made me give them their well deserved 5 stars. The owner actually babysat my little fish. Yes he did. Three years ago we bought our first house in Levittown and I didn't know what to do with my 20 gallon tank and five little fish who at that point had lived past a year. He said he would actually keep our fish in a separate tank until we set up the tank in our house. When we went back to pick them up a few days later, there they were, swimming around happily. And - NO CHARGE for the babysitting. Well, unfortunately, our tank is now empty but one day we will set it up again and I will be back to Total Aquariums. Oh, if you do go there, check out the live Alligators in the front of the store. Great for the kids!!
