I'm glad Dredgesclone posted, because it caused me to re-read this thread again. Several fish species have been tossed about, and I'm not sure what is or isn't under consideration. But I completely agree on the BH; six is going to fill your 36g (I assume a 3-foot tank?) and I believe there are also five danio of some sort? That is it for upper fish. A group of 5-6 corys could be added. But nothing more in my view.
Sorry I was confused yesterday.:duh:
