The Fzone Anata Series sets a high standard for small-scale aquascaping enthusiasts who demand visual clarity. This 2-gallon tank utilizes NovaClear ultra-white glass, which effectively eliminates the distracting green or blue tint found in standard glass to achieve a massive 91.5% light transmittance.
