tadpole tank switch around

SpermLeaf the tadpole has nice looking back legs now , and before ya know it he will be a frog , of some sort .. so i am thinking about how to setup his tank for when he has legs . i have been looking in books for ideas , but so far nothing has sparked my imagination yet . i hope he isnt going to turn out to be a tree frog , because then i will have to get a top for the tank ..
