6 Best Rimless Aquariums in 2024: Reviews & Top Picks

GankPike rimless aquarium

If you’re looking for a modern, sleek, and simple fish tank, then you might be interested in what a rimless (also known as a “seamless”) aquarium has to offer. These tanks are made of ultra-clear low iron glass and have no bulky plastic brackets or thick rims that often stand out in standard glass aquariums. Rimless tanks may be on the pricier side, but they’re definitely worth the investment if you want a clear and attractive-looking tank to turn into a lavish aquarium with either freshwater or salter water fish and plants.

We have reviewed some of the best rimless tanks on the market and chosen them specifically for the quality and features these tanks have to offer.

    Features Integrated filtration space

    The best rimless tank for the money is the LANDEN 40C Rimless Aquarium with Rear Filtration Chamber because it is not only affordable for what you get, but it includes an integrated filtration space and water flow chamber too.

It comes in two different sizes, 10 and 16 gallons, and will work for both saltwater and freshwater aquariums.

The glass joints are made with a high-quality silica gel for a smooth and rimless appearance, while the filtration system is detachable, and the outlet flow nozzle can be adjusted or detached.

    Dimensions 17 × 8.66 ×  8.66 inches
    Gallons 6 gal
    Features Black nano leveling foam mat

    Our premium choice is the Ultum Nature Systems Rimless Aquarium Fish Tank because it has a neat modern appearance and a standard cube shape which can easily fit onto an office desk and other small places. This rimless tank comes in four different sizes, but it does not exceed 4.6 gallons so it should be used for smaller fish only. The overall quality of the tank is good, with 91% clarity from the diamante glass, high-quality German silicone that gives this rimless tank a smooth appearance, and 45° mitered edges.

    It also includes a black nanofoam leveling mat which can be used underneath the tank to keep it sturdy and leveled on most surfaces.

    • Made of high-quality materials
    • Modern appearance

    4. GankPike Curved Corner Glass Rimless Aquarium

    GankPike 8-Gallon Curved Corner Glass Saltwater Aquarium

    Dimensions 8 × 11.8 × 11.8 inches
    Gallons 8 gal
    Features Lid, protein skimmer, light, heater, thermometer

    This 8-gallon GankPike Curved Corner Glass Rimless Aquarium is made of low iron glass. It is suitable for saltwater aquariums as most of the inclusions in this tank are better suited for reef aquariums. This tank has a curved corner and rectangular shape with a chamber at the back where it includes space for filtration media. This aquarium includes a lid, protein skimmer, LED light, heater, and an LCD digital thermometer which makes it worth the price.

    However, these additional items can make this aquarium look bulky and heavy. It is made of low iron glass for maximum brightness and clarity and visible light transmittance of 91.5%.

    Pros
    • 5% clarity
    • Affordable
    • Includes all the essential items for a saltwater tank
    Cons
    • Bulky appearance
    • Too small for most marine fish

    5. JBJ Rimless Desktop Aquarium

    JBJ Rimless Desktop 10 gallon aquarium

    Dimensions 6 × 10.6 × 10.2 inches
    Gallons 10 gals
    Features LED light and filter

    The JBJ Rimless Desktop Flat Panel Aquarium is a stylish option that looks perfect on desktops. It is equipped with a Lyra 9 watt LED lighting fixture that has two different color options. It also includes a clip-on biofilter that can be plugged in, so this tank should be close to an electrical outlet as the filter’s wire is not very long. The filtration media for the filter must be purchased separately and the lighting system has an adjustable brightness setting.

    Although it is a rimless tank, the glass seems to be prone to scratching more easily than other rimless aquariums that are made of low-iron glass.

    Pros
    • Included light has different settings
    • Includes a filter
    • Ideal for both saltwater and freshwater aquariums
    Cons
    • The glass scratches and chips easily

    Features White leveling mat

    This Hiro Aquatics Nano Tall Rimless Aquarium has no frame and comes in a cube shape. Its small size is better suited for fish like bettas and other nano fish. There is no brand logo on the glass which provides you with a clear view into your tank. The tall design saves space which makes it easy to place on countertops and desktops. It is built with low iron glass for an extra clear view inside the aquarium, making it transparent.

    This tank also comes with a white leveling mat to help relieve pressure and increase the stability of the tank once it has been filled with water. It comes in three different sizes but does not exceed 5 gallons, placing it on the smaller side.

    Pros
    • Clear, low iron glass
    • Includes leveling mat
    • Space-saving design

    Buyer’s Guide: How to Buy the Best Rimless Aquarium

    What is a rimless aquarium?

    Rimless aquariums are constructed of low iron glass that gives a higher level of clarity and transparency to aquariums in comparison to the blue-green hue that can be seen when you look at the glass panels of standard glass tanks. This enhances the visual appearance and sleekness of a rimless tank, and they look less bulky and thick than normal glass. Most low-iron rimless aquariums will have a high-grade silicone to connect the panels.

    There are many different types of rimless aquariums, such as plain ones or combo sets that include a filter, heater, or light. Most rimless aquariums will include a leveling mat that can be placed underneath the tank to avoid putting excess pressure on the delicate glass panels.
