.5 Half Gallon Square Jarrarium Setup

The square tank, an introductory tank for nearly any aquarist. But hardly any serious aquarist would use a 1 gallon tank, much less a .5 gallon tank. Until now. I saw this glass square on sale, in Petsmart, listed as a tank for a betta. Which is horribly inaccurate, but actually usable for different kinds of life! In this square Jarrarium setup, I sought out for something minimal, but also jungle-esque, and with a piece of driftwood as the centerpiece. Below you’ll find a list of my materials!

  1. Does anyone know what happened to Dime Piece LA celebrity streetwear brand? I am unable to check out on Dimepiecela site.
