can a frog live happily in an environment, short answer, yes. but they would be even happier in a viv with live plants. think about it, if silk plants were "just as good", we'd be replacing all the rainforest we destroyed with them. ok, a stretch, i know, but no one will ever convince me that silk is the better way to go. and to elaborate on Adam's post, live plants not only clean the air, but add much needed oxygen to the tank. oh, and the collector part is 100% true.....i am a living example...LOL
