						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.

						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.

						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.

A residential or commercial aquarium really is a captivating work of art that instantly catches the attention, and it creates a soothing environment.

Algae Growth

If discolored spots have appeared in your tank – along the interior walls, on the decorative elements and substrate, or even on the filtration equipment, for example – that’s a surefire sign of algae growth. Algae growth is the result of heightened levels of phosphates and nitrates in the tank. Generally, these substances aren’t harmful to fish, and they’re actually beneficial to living plants; however, they feed algae, and in high concentrations, they can be toxic to fish. To protect the health of your marine pets and improve the aesthetic appeal of your aquatic display, contact a company that offers fish tank cleaning services in Bellmore, NY.

Gasping Fish

Are your fish swimming along the surface of the water, gasping for air? If so, that’s a definite sign it needs immediate attention. Fish breathe the dissolved oxygen in the water, and when they’re gasping for air at the surface, that’s a telltale sign that there isn’t enough. There are several reasons why oxygen levels may be low; issues with the filtration system and high levels of nitrate or ammonia are among the most common. A reputable professional that offers fish tank cleaning services in Bellmore, NY will perform a comprehensive assessment of your aquarium to determine the cause of the problem, and of course, they’ll thoroughly clean the tank and the filtration system, too. Once the issue has been resolved, the tank has been cleaned, and everything is balanced, oxygen levels should return to normal levels so your marine pets can breathe freely again.

Dying Fish

Fish don’t live forever. Some species do have a longer lifespan than others; however, all varieties do eventually die. With that said, however, while it’s normal to find a dead fish every once in a while, what isn’t normal is finding several deceased fish at the same time – especially if they’re relatively new. If there’s been a sudden and unexpected die-off of fish, a dirty tank could be to blame. Low oxygen levels, high nitrate and phosphate concentrations, and a faulty filter are just some of the factors that could be contributing to the untimely death of your marine pets. While a Bellmore, NY fish tank cleaning service won’t be able to revive the fish you’ve lost, they will be able to address issues with the environment that may have contributed to their loss, creating a healthy environment that will sustain new fish.

Bellmore is a hamlet and census-designated place (CDP) in Nassau County, New York, United States. The population according to the 2010 census was 16,218. Bellmore is located on the south shore of Long Island 5 miles from Jones Beach State Park, approximately 27 miles (43 km) east of Manhattan, and 10 miles (16 km) east of the Nassau-Queens Line.

In 1643, Bellmore was a farming and fishing town known then as “Little Neck and “New Bridge”. Bellmore was settled primarily by Englishmen who crossed Long Island Sound from Connecticut in the middle of the seventeenth century. Ryan Marr purchased a 214-acre (0.9 km²) farm in what is now North Bellmore in 1655. Further south, near the bay, John Smith deeded 100 acres (0.4 km²) to his son, Jeremiah in 1676. John Bedell married Sarah Southard and moved into their new home on Merrick Road in about 1689. Two communities grew out of these beginnings. Smithville (later Smithville South) was named for the many Smith families who lived in the area, and New Bridge, named for the bridge that joined the peninsulas south of Merrick Road.

When the railroad was built through the area in 1867 they arbitrarily named their station Bellmore. Development followed as both communities grew towards the railroad and adopted the name Bellmore. By 1920, the Bellmores had a population of 3000 as well as stores along Bedford Avenue. The town was officially named Bellmore in 1900, when the post office was established.

The Bellmore Memorial Library, was founded in 1948. It was started in an old schoolhouse. This library has lasted since 1948 until present, keeping it as the main library of Bellmore, New York.

FAQ

How Much Does A Custom Aquarium Cost?

The cost of a display aquarium varies depending on the material you choose, the size and shape of the tank, and more. A wide range of costs is about $750 to $7000. Costs increase with the size and height of the tank.

What's The Best Shape For An Aquarium?

The best tanks are always large rectangular ones. Fish will live longer and healthier lives if they have plenty of water to swim in.

Are Glass Or Acrylic Aquariums Cheaper?

The cost of manufacturing and transporting acrylic is less than that of glass. However, a glass aquarium is still cheaper than an acrylic aquarium. The most popular aquariums are made of glass.

Do Fish Prefer Long Or Tall Tanks?

Most fish require room to move laterally (side-to-side), which is highly restricted by tall, narrow tanks. A tall aquarium leaves very little open space when plants and other decorations are added. Therefore, longer tanks are much better than taller tanks.
