I ordered a VISIO custom glass tank, which you can see here
http://www.orchidboard.com/community...tml#post336380. The company website is
Advance Aqua Tanks. They are a US company, so no issue shipping to the US. I did supply very precise scale plans to them, drawn up in InDesign. They do drill holes and made the custom internal divider at an angle, plus the support for the rock piece for the waterfall. You will have to order it through some kind of pet-shop, aquarium dealer near you.
If you want to do acrylic, then you can drill your own holes. I did smaller ones with regular drill, larger ones with a drill bit used to cut holes for door locks.
Be very careful drilling those holes. Too much pressure on the drill can crack the piece. So possibly practice first on a small trash piece, before working on the actual tank.
Drilling glass is best left to the pros. I did provide the actual pieces for what should go through the holes (bulkheads, float valve, etc.) so that they can measure the fittings themselves and drill accordingly. No misunderstanding possible. The rock was cut after the fact.
