well, right now, there is nothing in that tank. i did have my dart frogs in there, but i gave the frogs to my girlfriend. but im moving in with my girlfriend this weekend...so the frogs get their tank back. the 'false background' is just great stuff expandable foam. you get any rocks or logs you want in the background. lay the aquarium on its backside. lay the logs and rocks the way you want them... then just start spraying foam around the logs and rocks and all across the back of the aquarium. dont spray too much however. just spray an inch or so layer onto it. the stuff expands GREATLY!!! you can always use a razor blade to trim the foam once it hardens. oh.. dont touch the foam when its wet. it takes forever to get it off your hands. the substrate on the foam is just peat. there is a glue called Weldbond that is non toxic and water resistant. just mix the glue with the peat and water till its a mud consistency. make sure there is enough glue. squeeze the peat and if it runs white and thin, its perfect. with the aquarium still on its back, you just paste the peat on there. it takes about a week or so to dry completely depending on temp. after that, add plants and whatever else you want. you can also set up false bottoms or a pond area with the same ideas shown in other tanks on the forum. be creative and youll be surprised at what you can do. im working on a c. orientalis tank that is looking good so far.
