Sweet looking tank, and I'm digging the plant selection. I take it you have the patience of a saint? I don't think I could wait long enough to have decent cover by the erios and buces. I have a buce in my 2.5 and I've had success (relatively) growing it, unburied and while under 15 watts/gallon, it is growing underneath some overhangs which gives it low to medium lighting. Best of luck!
