Rimless Aquariums
Rimless aquariums are the classic aquascaping look: no plastic frame, just clear glass edges. They also change which lights, lids, and stands will work with your setup.
What matters most
Glass clarity and thickness
Low-iron (ultra-clear) glass shows less green tint, and thicker glass is needed as tanks get taller. Follow the maker's guidance on support.
Level, flat support
Rimless tanks typically need a level, flat surface and often a leveling mat. Water is heavy, so use a stand rated for the full filled weight.
Lights and lids
Because there is no rim, you will need a light with a rimless bracket or a hanging kit. Jumpy fish may need a glass lid made for rimless tanks.
Check before you buy
- Is your stand rated for the filled weight and perfectly level?
- Does the maker require a leveling mat?
- Does your planned light include a rimless mount?
- Do your fish jump? If so, plan a lid.
You prefer a framed tank with a fitted hood, or your livestock is prone to jumping and you do not want to fit a lid.
