Want to find a little pico (jbj or fluval pico would be about perfect) to try and tinker with. Rather have a rimless tank as oppposed to a nano/bio cube thing. Let me know what cha got.
Just get yourself a new one and then start "ruining" like I did. You can check out the build thread for it on RC here is the link. This is still running today, though it has different things in it than in the pictures. KhensuRa has seen it in action.
