How to make your own mini tank?

Any place that sells plexi glass or acrylic will have it. Also I'm sure you could find it at a hardware store.

If you want really clean seams with acrylics there is a method called flame polishing which you may want to look up, I built a small 40g planted about 7 years ago when I built it I did this and the comparison to unpolished is unmatched and I'd highly recommend it. Basically you take a blow torch and lightly flame the cut edges to smooth out the blade marks.
