Thanks guys. I tried to get a pic of the bleeding heart tetras but they just don't stay put. There's some pretty cool rocks in there. I'll take some individual pics of them, a couple are very interesting. One has a fossilized centipede or worm in it, along with some sort of snail.
Shadow- That is pool filter sand, aka Silica sand. One 50 lb. bag is all it took to get to it's current level. PFS is hard to find this time of the year, but when spring time comes I'm going to add more and raise some spots in the tank to get a "hill" like effect.
