Just wanted to say two things...
1.) Nice looking tank. I think the 40 breeder dimension are just about perfect for learning how to aquascape well. Good choice there.
2.) I grew up in Midland (MHS, '93) and get back there just about every summer - for the life of me, I can't think of any place in that town that sells decent aquarium equipment or livestock, let alone honest-to-goodness aquatic plants. Where are you shopping?
