Heres a pic of my tank, sorry it isnt too great. Basically, I have some PVC Scheduel 40 pipe set up to hold up a piece of flagstone I got at a local garden supply place. On the bottome, I have some Tiger Rocks and some larger river stones. I have also put in a few plants, as of now, Reyna is yet to eat them but she has been trying them out. She seems to really enjoy the one with large leaves, she always layes up on the leaf and breathes and stuff. Also, there is a small plateau in there on teh PVC as well that I put any food that sinks on for her so it doesnt get lost in the rocks, also, it is good for the cuttlebone when it sinks cause she seems to like to eat it off of that better than from the surface of the water.
PS... I stole the PVC idea from someone, sorry I dont remember who.
