Where can i get panels like this

Regardless of what material you use, it won't just float there. You'll need to build a 2x4 skeleton that will hold all the panels in place

Here's an idea of what I'm referring to. I love the look you are trying to achieve, very classy and elegant and makes the tank just pop!

Marko, totally agree it needs a skeleton. This system offers exactly that...no I'm not associated or affiliated with this group, but I've seen their work on many projects and its amazing what can be done with this system, don't have to have straight lines in the framing, angles, odd shapes etc.
