omg, do I know learning. My son got me a exo terra, a hood and money for a frog for Christmas. I have been taking an intense crash course in vivarium ecosystems for... had to think about it... two weeks. My project this weekend is to strip this down and redo it properly. I'm consumed with it, to be honest. I couldn't sleep last night because I was redoing the plants layout over and over in my head. Ridiculous, and yet I cannot remember the last time I had this much enjoyment and FUN!!!
