Looking for cave ideas

Thanks, I posted a few more pics in the photo gallery.

I am actually really enjoying the tank at the moment, the oto's are keeping the plants very green. The black neons are doing a good job of schooling at the top, the rummys school nicely along the mid-lower levels, the angel is all over the place, and the new ram's are acting very curiously getting to know their surroundings.
