You might remember FistaFiltration, the UK-based acrylicsmith we covered in 2012. We were recently teased with an interesting take on the nano aquarium from the company dubbed the FistaFiltration Nano Drop aquarium. The nano-sized drop tank holds around 70 liters (around 18 USG) and was designed to be used with a sump. From the image above, you can see the two tubes on the upper section, these serve both as a stand to support the tank and hide the plumbing. In the production version, these tubes will be colored to hide the plumbing. These will be available shortly in the UK for £249.99.
