I hope you don't have any leaks. usually alot of glue leaks more than a single bead of glue. be sure glue is dry before you add everything or the divider will shift from the weight of the dirt and it will leak. cork bark is good for the frogs to hide under if you half bury one end of it you have a good cave. or bury a large piece of bamboo. your setup sounds ok to me. background on 2 or 3 sides?
