Hey Lynn, Thanks for the tip on the dispenser! I just found a 3 gallon one for 34$ on the cheap. It looks like it can hold a few small bromeliads. I'm thinking I can get a small cork tube or some drift wood to run vertically up the center, and drill holes in it to mount the plants. For the drainage layer I'm going to use large polished stones and try to grow live moss over them. I'll probably put some pothos in there too to give them something more to climb and sleep on. I'll also place a few small cork pieces around the bottom to provide lots of good hiding places. I'm going to give this setup a try, and see how the frogs like it. I've decided on D. Imitator. They are only about 3/4 inch, and are more hardy and out going than other thumbnails. I also read they get along pretty well. I'm fixin' to go shopping for all the decor. I'll have to post some pictures once I get it set up. Thanks so much for all the help!
