I am getting my tank ready to add an eel to my tank. It will most likely be a peakock. I removed a lot of the grass I had growing on the bottom of my tank leaving mostly sand. Other than a few swords growing in the rear corners it is bare. I want to build a few caves but am not very artistic. I was hoping I could see some pictures to give me some ideas. I have a 125gal if that helps. Any ideas?
