Hexagon Aquariums

All our standard and special aquarium sizes, including our unique hexagon-shaped aquarium design, now have optimized engineering to determine the minimum thickness required for each panel of glass. We don’t settle for a one-size-fits-all formula but rather optimize every panel in the aquarium based on engineering standards based on your needs.

Custom Aquariums’ professional engineers use advanced pressure rating formulas to optimize every aquarium to have a minimum safety factor of 2.3 (standard in the industry as a minimum, but ours are even stronger because of the aluminum frame system). Some of our aquariums have a safety factor of 3.5. Using this technique, we can achieve the highest strength at the lowest cost – so don’t be surprised if our prices and weights are a lot better than other aquariums out there of the same size. Of course, these are minimum standards. You are always free to upgrade any panel for any reason for additional peace of mind.

Our unique, six-sided hexagon aquariums and island aquariums make excellent habitats for many types of aquatic species, including fish, coral, sharks, rays, turtles, and more! These unusual tanks are usually placed in the middle of the room for easy viewing and make a truly eye-catching addition to your home, office, or waiting room.

Our hexagon fish tanks are available as rimless or framed. A rimless aquarium lets viewers look down into the fish tank and see the teeming aquatic life! If you choose our high-strength aluminum frame on the top, you can rest assured knowing that you have one of the strongest aquariums on the market.

If you are looking for a large aquarium, we can make it for you. We specialize in making big custom aquariums. We often make aquariums over 500 gallons. Your new hexagon aquarium could be an awe-inspiring centerpiece in your home or office!

We also offer hexagon fish tanks in the amphibious style, making it suitable for turtles and various amphibious creatures to enjoy a half-land, half-water habitat!

Aquarium Shapes

 Our custom aquariums come in more than just a hexagon. You can order various shapes and sizes, including squarerectangularpentagon.

Rimless Hexagon Shaped Aquariums

We can also customize most of our standard glass aquariums to be made as rimless glass aquariums, even the hexagon-shaped aquarium! The rimless aquarium works great for frag tanks, island tanks, turtle tanks, and more! Custom Aquariums’ classy polished beveled edge and superior craftsmanship make our rimless tanks the premier rimless brand on the market today. Our Majestic stands come with center supports, so even our largest rimless glass aquariums are well supported. We also have our own unique, innovative center concealment column to assist in adding plumbing, such as our H2Overflow and Siphon Stoppers, to make filtration easy for island tanks.

Glass vs Acrylic Aquariums

There are advantages and disadvantages to using either glass or acrylic for your hexagon-shaped aquarium! The Custom Aquariums team has spent a great deal of time evaluating what type of custom aquariums to use. We have immediate considerations of the installation difficulties to consider and the long-term viability of our investment. However, once you analyze the difference, the choice is quite clear. When it comes down to the decision of glass vs. acrylic aquariums, most often, you are sacrificing a long-term benefit of glass aquariums in exchange for short-term use of acrylic aquariums. Please see our glass vs. acrylic page for more information on our evaluation of the glass versus the acrylic hexagon-shaped aquarium option.
