Thanks for the compliment! Ernie n Bert hang out a LOT on the shelf that I siliconed to the side, up there on the right. It's acutally an Zoo Med floating turtle dock (small). They prefer to be up high, for sure. The plants are hardy and take a heckuva beating every night, but being solidly planted in the substrate, they are doing very well at holding their own. I thought about putting a water feature in, but they are tree frogs, and they are not swimmers, they are butt soakers, lol.
