Pros
- Exceptional water clarity with minimal color distortion for viewing and photography
- Strong build quality with clean silicone seams and 5mm thick glass
- Sleek rimless profile perfect for aquascaping, shrimp and planted setups

The Ultum Nature Systems 45T is an 11.3-gallon rimless aquarium measuring 17.71 x 11.02 x 14.17 inches. It is built for aquascapers, planted tank hobbyists and nano fish keepers who want high clarity in a compact tall format.
Standout performance comes from the 91% clarity low iron glass that keeps colors bright and true. The 45-degree mitered edges reduce visual distortion, so fish, plants and hardscape look sharp from the front and sides.
Design follows a minimalist golden ratio with a clean rectangular shape and no bulky rim or bracing. Build quality feels premium with 5mm thick glass, neat German made silicone seams and an included foam leveling mat for stability.
Drawbacks are typical for rimless tall tanks. The open top means more evaporation and the vertical shape is less suited to large, active swimmers. It also needs a level stand and gentle cleaning to keep the glass pristine.
For hobbyists focused on aquascaping and visual clarity, this is an excellent choice. It combines refined looks, solid construction and immersive viewing in a versatile 11-gallon size.

Allcolor 7 Gallon Rimless Aquarium Tank
Pros
- Outstanding clarity that makes aquascapes and green plants look vibrant and natural
- Modern rimless silhouette earns frequent compliments as a display piece
- Solid 5mm glass and precise joints provide confident structural integrity
- Thoughtful bundle with lid and mat simplifies setup for beginners
Cons
- Glass lid does not seal tightly and may leave small gaps on sides and front
- Heavy glass cube needs a fully level, sturdy stand and careful placement
- Fragile in transit, unpack carefully and water test seams before adding livestock
The Allcolor Classic Silhouette 7 Gallon is a rimless cube aquarium measuring 11.81 inches on each side. It is designed for freshwater aquascapers, planted tank hobbyists, betta keepers and ornamental shrimp breeders who want a compact minimalist display.
In daily use, the low iron glass delivers a noticeably clearer view than standard glass with no green cast. Colors stay true, green plants look richer and hardscape details remain sharp from every angle, which is ideal for aquascaping photography.
Build quality centers on 5mm exhibition grade glass with hand finished, near invisible silicone joints. The edges are polished smooth and beveled for safe handling, while the included glass canopy and bottom mat add stability and help limit evaporation.
There are tradeoffs to note. The lid fit is a bit loose and can leave gaps, so it is less suited for jumpers or humidity sensitive setups without modification. As with any rimless glass tank, it must sit perfectly level and should be inspected and leak tested after shipping.
Overall, this is a strong pick for anyone seeking an affordable entry into high clarity rimless tanks. If you want a beautiful nano cube for plants, shrimp or a single betta and you value clean design over a tight sealing lid, it delivers excellent visual impact.

How They Compare
Tank Size, Footprint and Swimming Room
The UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L measures 17.71 x 11.02 x 14.17 inches, which is listed as 45 x 28 x 36 CM, with 5mm glass thickness and a capacity around 11.9GAL in the title and 11.3 Gal in the 45T spec line. The Low Iron Glass Ultra Clear Rimless Aquarium measures 11.81 x 11.81 x 11.81 inches, which is 30 x 30 x 30 cm, with 5mm glass thickness and a 7 Gallons capacity. For cherry shrimp, that difference in length and height changes how much substrate surface, plant mass and grazing area you can support.
When you compare the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L and the Low Iron Glass Ultra Clear Rimless Aquarium side by side, the rectangular tank gives your colony a longer front to back run for foraging and better separation of moss, wood and open feeding zones. The cube keeps everything close, which makes it easy to watch shrimplets but leaves less room for a colony to spread out as breeding picks up. If you plan to pair either tank with active soil, read our Active Soil + Substrate overview so your buffering and water change routine matches the volume you choose.
Glass Clarity, Silicone Work and Edge Finish
The UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L is built with low iron 91% clarity glass and 45-degree mitered edges that are meant to reduce the green tint and keep corners visually clean. The Low Iron Glass Ultra Clear Rimless Aquarium also uses premium low-iron glass with a rimless design for true to life color, plus multi-step polished beveled edges that feel smooth during trimming and water changes. Both aim for that floating water look that makes red cherries pop against green plants and dark substrate.
For build quality, the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L uses German made silicone rated for moisture and durability, which keepers value for long term peace of mind. The Low Iron Glass Ultra Clear Rimless Aquarium also uses top-tier German silicone for tensile strength and anti-aging durability, with thin uniform near-invisible joints applied by hand. In daily use you will notice the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L shows a sharper mitered corner, while the Low Iron Glass Ultra Clear Rimless Aquarium shows a softer polished bevel that is forgiving when you are scraping algae near the seams.
Lid, Mat and Evaporation Control
This is the clearest out of box difference between the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L and the Low Iron Glass Ultra Clear Rimless Aquarium. The UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L includes a leveling mat for support and stability, but no canopy is listed in the specs, so you should plan for open top evaporation. The Low Iron Glass Ultra Clear Rimless Aquarium includes one set of matching top glass canopy with clips and a protective bottom cushioning mat, which gives you a more complete starter package for covering the tank.
For cherry shrimp, the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L with open top gives strong gas exchange and easy access for feeding dishes and trimming, but you will top off more often and you may see mineral lines on the glass. The Low Iron Glass Ultra Clear Rimless Aquarium with its glass canopy slows evaporation, steadies temperature swings in small volumes and helps keep tiny shrimplets and floating plants where they belong. If your room runs warm or dry, pair either choice with careful airflow planning from our Heater + Chiller + Fan resources.
Aquascaping Layout and Daily Maintenance
The UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L at 14.17 inches tall suits upright wood, tall crypts or rotala walls behind a low carpet where cherries can graze at different levels. The Low Iron Glass Ultra Clear Rimless Aquarium at 11.81 inches on all sides suits a central stone or small driftwood island with moss all around, which looks balanced from three sides on a desk. Both tanks use 5mm glass, so aquascaping tools, small sponge filters and nano lights are easy to position without fighting a plastic rim.
In cleaning, the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L gives you longer glass runs to wipe, but waste spreads over a larger footprint so parameters tend to shift more slowly between water changes. The Low Iron Glass Ultra Clear Rimless Aquarium is quicker to wipe and vacuum, yet keepers commonly report small cubes need more frequent small water changes to stay stable. For breeding focused layouts, our shrimp substrate setup ideas for breeding tank guide can help you plan soil depth and hiding spots for either footprint.
Which One Should You Get
Choose UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L if you want a larger cherry shrimp display with room for a growing Neocaridina colony, taller plants and a proper hardscape with foreground and background zones. Its 17.71 x 11.02 x 14.17 inch rectangular form and 91% clarity glass with 45-degree mitered edges suit a living room or office where viewing clarity matters. You should be comfortable managing an open top tank with regular top offs and adding your own lid or mesh if you keep floating plants or very active shrimplets.
Choose Low Iron Glass Ultra Clear Rimless Aquarium if you want a compact 7 Gallons cube measuring 11.81 x 11.81 x 11.81 inches for a desk, bedroom or first cherry colony. Its included top glass canopy with clips and bottom cushioning mat make setup simpler, and the polished beveled edges feel friendly during frequent trimming. You will trade total colony space and scape length for easier placement, lower evaporation and a tidy all in one look that works well for a focused red cherry display.
My Experience
I have kept red cherries in a tank like the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L on a solid stand with the included leveling mat underneath, and the extra height made feeding and molting behavior much easier to observe. The mitered front corners stayed clear for photos, and the longer footprint let me keep moss on wood at one end and a feeding dish at the other without crowding berried females. I needed to top off more often than with a lidded cube, but the colony bred steadily once the biofilm matured and I kept water changes small and consistent.
Who Should Skip Both
These two glass boxes are not ideal for keepers who need a complete plug and play kit with filter, light and lid in one box, or for anyone running a high count breeding rack where standard rectangular footprints and shared air matter more than display glass. They are also not a good fit if you need a tall paludarium style tank for emersed growth or a very large colony tank where waste load needs much more water volume. In those cases, start with your system goal first, then revisit mineral and water prep in our GH/KH Mineral + RO Water section.
Frequently Asked Questions
Is the UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L too big for first time cherry shrimp keepers?
No, its 11.9GAL volume and 17.71 x 11.02 x 14.17 inch size can actually make learning easier because parameters shift more slowly than in very small tanks. You will need a cycled filter, hiding spots and a regular small water change routine. Plan for evaporation control since no canopy is listed.
Does the Low Iron Glass Ultra Clear Rimless Aquarium come with a lid for shrimp?
Yes, it includes one set of matching top glass canopy with clips plus a protective bottom cushioning mat according to the specs. The canopy helps limit evaporation and keeps floating plants and shrimplets inside. You can still leave a small gap for airline tubing or a feeder if needed.
Which tank shows cherry shrimp red color better for 2026?
Both use low iron glass to reduce green tint, so reds look truer than in standard glass. The UNS Ultra Clear Rimless Tank – 11.9GAL | 45.3L lists 91% clarity glass with 45-degree edges for edge to edge viewing. The Low Iron Glass Ultra Clear Rimless Aquarium relies on polished low iron panels that also keep colors clean in a smaller viewing box.
