Best Rimless Aquariums for Aquascaping, by Footprint (2026)

Rimless low-iron tanks for aquascaping, grouped from nano to 60 cm and larger, with exact dimensions, volume, glass thickness, and leveling notes.

The short answer

Start with the footprint you have room for, then pick a height. For a desk, the UNS 5N (36 x 22 x 22 cm) and LANDEN 30C cube (30 x 30 x 30 cm) are the small options. At 45 cm, the LANDEN 45P is the classic low shape and the UNS 45T adds height. The UNS 40C is a 40 cm cube for viewing from several sides. At 60 cm, you can choose a shallow carpet tank (UNS 60S), the classic 60 x 30 x 36 cm size (LANDEN 60P or Lifegard Crystal 17.11 gal), or a deeper and taller tank (UNS 60T, LANDEN 60H). None of these list a lid as included.

Who this guide is for

This guide is for aquascapers buying a low-iron rimless tank who want exact sizes before planning hardscape, lighting and a stand. Without a top frame, a rimless tank depends on the glass, the silicone, and an evenly supported base. Our rimless aquarium buying guide explains glass thickness relative to height, leveling mats, stand load ratings, and what to inspect when the tank arrives.

These tanks suit both low-tech and CO2-injected setups. The main thing that changes with your choice is height. A taller tank needs a stronger light to reach plants at the substrate. A shallow tank leaves less room for filter intakes and heaters.

The UNS 5N measures 36 x 22 x 22 cm (14.17 x 8.66 x 8.66 in) and holds 17.4 L (4.6 US gal), with 5 mm low-iron glass and mitered edges. Some retail listings call it a 5-gallon tank with thicker glass. The UNS size guide gives 4.6 US gal and 5 mm, and those are the figures we use. A leveling mat is included, and UNS glass lids are sold separately. With this little water, parameters change quickly, so top off evaporation often and test regularly.

A cube can be viewed from more than one side, but it gives you less front-to-back depth than a longer tank does.

The 45P measures 45 x 30 x 30 cm (17.7 x 11.8 x 11.8 in) and holds 10 US gal (about 38 L), with 5 mm glass and an EVA foam leveling mat. Amazon's dimension data lists the depth as 10.63 in, but LANDEN states 11.8 in (30 cm), so we use the maker's figure. The 30 cm height works with modest lights and is easy to reach into for planting.

The UNS 45T measures 45 x 28 x 36 cm (17.71 x 11.02 x 14.17 in) and holds 45.3 L (11.9 US gal), with 5 mm glass. It's 6 cm taller than the 45P but 2 cm shallower front to back. That suits vertical stem groups and taller rockwork, though the narrower depth gives you less room to build perspective.

The 40C is a 40 x 40 x 40 cm (15.74 in) cube holding 64 L (16.9 US gal), with 6 mm glass. Its 40 cm height makes it harder to plant and maintain the back corners, so plan on long tools. It also needs a light strong enough for that water depth.

The 60S is a shallow tank: 60 x 36 x 18 cm (23.62 x 14.17 x 7.08 in) and 38.8 L (10.2 US gal), with 5 mm glass. The wide footprint and low water column suit carpets and emersed-style layouts. UNS points out that the shallow depth makes it harder to place filter intakes, outflows and heaters, so plan your equipment before you build the hardscape. It fits UNS glass stands made for 60 cm tanks.

The 45 cm depth gives the most front-to-back room for layered layouts in this list. It also holds the most water of any tank in this list, so your stand needs to be rated for that load. LANDEN sells a fitted 4 mm glass lid separately.

Alternatives and when to skip buying

If you keep fish that jump and can't fit a lid, a framed tank with a matching hood may be the safer choice. If your current tank is level, sound and the size you want, a rimless upgrade mostly changes the look, not how well plants grow. Budget for the stand, light, filter and lid along with the tank. You can compare more options on the Rimless tanks: what to check before you buy ↗ hub, or match a tank to your plans with the setup finder.

How we chose

Each tank was matched to its Amazon listing by the maker's model name and size. Dimensions, volumes and glass thickness come from manufacturer documentation, and where a listing disagreed, we used the maker's figure. Only tanks rated 4 stars or higher on Amazon when we checked made the list. We looked at fit before anything else: footprint, height, and the leveling and support guidance each maker provides. We haven't tested these tanks hands-on, and we don't rank or score them.
