I second what Thomas712 says. You would be better off to check with this crowd before any tank purchase. It teaches you patience up front, which will save your tank and your money.
My independant piece of advice. Dont make decisions based solely on aesthetics.
I custom designed everything on my 125, including the tank itself. It originally came straight out of the wall, so you you could walk around both sides of the tank. To make this look better, I had the overflow box placed on one end of the tank. I learned the hard way that it takes a lot of creativity to get current to travel down 6 feet of tank. It works great now, but I could have saved myself a lot of time and energy by running it by this crowd first.
There are some brilliant folks on here. And their advice is FREE!!!!
