OK thats fine, I guess I'll keep things like xenia, shrooms, zoos, gsp, leather, and LPS. BTW what do you guys use as filtration on these types of tanks. I definately don't want to drill it and I don't really want a skimmer. I was thinking of just lightley stocking it, have some liver rock and just have a power head circulate the water. Do you think that will work?
