Aquarium, Samuel Guimarães's 64 L Planted Cube Aquarium. (Brazil)

Cubic shaped aquariums are rather difficult to set up right and establish a truly nice aquascape, but on the other hand, from further away this type tank is one of the most effective as a decorative piece on furniture. How about one of these in your living room?

Comments:	At age 13 (11 years ago) I had a 30 L tank for 2 or 3 years (starting with crayfish, fish and later turtles), which I ended up selling at the end of High School. At the time of fish population there were some cardinals, serpaes, swordtails (that spawned a lot, some grew and were sold to shops), pleco, black widows and a few zebra danios. UGF filter (argh), 500 L/h pump, heater with thermostat, river gravel, incandescent bulbs (sheesh), rocks. Total weekly water changes (hahaha, the water would get really dirty), I'd wash the entire tank, removed everything and washed gravel, rocks, everything. I barely treated the new water with anti-chlorine and no matter what, back inside went the poor fish again. How completely wrong it all was hehehe... Today I'm a biologist in graduate school in Belo Horizinte, where I currently live. I'd been practicing the hobby "virtually" for 7 years (following related forums here and there), and, after lots of dreaming (literally) about having an aquarium again, I decided to return to the hobby, but this time, doing things the right way (as much as po$$ible). Here's the result of some planning and lots of sweating hahaha (both for getting the $$, and for the canister and lighting which are DIY). Despite a few details, I'm very satisfied with what I've achieved so far.
