By utilizing a hollow, bottom-less design, this 2-gallon tank creates a striking levitating effect that makes your nano livestock look like they are floating in mid-air. The real magic lies in the NovaClear ultra-white glass. Because it uses low-iron content, you lose that annoying greenish tint found in standard tanks, achieving a massive 91.5% light transmittance.

It is a sophisticated piece of glass art designed for serious nano enthusiasts.
