Any ideas for a Cuban Tree Frog habitat

[bunnyhugger]

My tadpoles became little froggies a few weeks ago and I am handing off a few but will still have a few left. They are in a 12x12x24 terrarium right now but I picked up this 50g tank for them. Open to any ideas. I did look at going vertical with it but I don't think it would be stable. Even this way it gives them 21 inches of height and I could build up from it, perhaps a mesh tower.
