Ultum Nature Systems 25C
These rimless aquariums are carefully crafted using 91% clarity Diamant glass, a highly transparent extra clear glass with very little residual green color. The low iron content in the glass provides uninterrupted crystal clear visibility. The 45° mitered edges are bonded together using high performance German silicone specifically designed for aquarium construction.
Rather than following the conventional sizing of other rimless aquarium brands, our dimensions keep the aquascaper in mind by focusing on the golden ratio. The additional space makes it easier to achieve that sense of perspective and truly show depth in an aquascape. Each Ultra Clear Tank comes with a black leveling mat which is crucial so you don’t have to cut up your wife’s yoga mat.

Cube Rimless Aquarium
Symmetrical cube aquarium tanks are the perfect size for tighter spaces. This style of aquarium is ideal for livestock choices such as Betta fish, Neocaridina shrimp and smaller nano schooling fish species such as Tetras and Rasboras. Beginner or experienced hobbyist, a cube aquarium is a great start or addition to an existing collection of planted tanks.
MODEL VARIANTS: 16C, 20C, 25C, 30C, 40C
VOLUME RANGE: 1 – 16 Gallons
Nano Rimless Aquarium
Increasing in popularity, nano aquarium tanks are the miniature versions of standard sized aquariums. They’re ideal for small displays such as a store countertop, nightstand or console table. With horizontal space, they allow for increased depth perception and creativity as well as swimming room for smaller species of fish and shrimp.
MODEL VARIANTS: 3N, 5N
VOLUME RANGE: 3 – 4 Gallons
Standard Rimless Aquarium
The most common aquarium sizes fall under the standard category. These consist of aquarium tanks ranging in sizes from 10 gallons to 100 gallons and up. These tanks offer a large amount of room for creating larger than life aquascape layouts. Common fauna choices are large schools of nano fish, smaller Cichlids, Gouramis, Angel fish, Discus and other medium sized tank inhabitants. Slightly on the larger size, they are a great canvas for unique nature aquariums.
MODEL VARIANTS: 45U, 60U, 75P, 90P, 90U, 120P, 120U, 180U
VOLUME RANGE: 9 – 156 Gallons
Long Rimless Aquarium
Long aquariums provide wide panoramic views and allow for longer aquascape layouts due to the generous amount of horizontal ground provided. Their elongated structure calls for elevated creativity and innovation. Nano schooling fish such as Tetras and Rasboras are ideal as they prefer plenty of horizontal swimming space to explore. Like the others, our long aquariums are clean, sleek and are a unique way to introduce a nature aquarium into any space.
MODEL VARIANTS: 60L, 90B, 90L
VOLUME RANGE: 6 – 21 Gallons
Shallow Rimless Aquarium
These provide a low panoramic view and require some creative aquascaping ideas as they lack general height. They make up for this with the amount of depth available and are overall wonderful canvases for growing aquatic plants emerged or would be excellent for a pond style layout. Lower level aquatic life such as Corydoras pygmaeus or Pygmy Cory Cats make great tank inhabitants as they tend to shoal together on the bottom of the tank and their curious sifting is fun to observe. Clean and sleek, the vibrant colors of the natural world held inside will come to life. No matter how small or big, these low aquarium tanks are the perfect way to introduce a unique nature aquarium into your space.
MODEL VARIANTS: 25S, 5S, 45S, 60S, 75S, 120S
VOLUME RANGE: 2 – 68 Gallons
Tall Rimless Aquarium
Made to inspire creativity or invoke minimalist aquatic plant keeping. These aquarium tanks feature taller glass panels and are the perfect tanks for lengthier aquarium plants or even aquatic lily display. This form factor also allows for elevated aquascaping.
MODEL VARIANTS: 16T
VOLUME RANGE: 1.5 Gallons
