I built this terrarium as a welcome distraction during my first year of law school in 1993. It was temperature and humidity controlled, it rained several times a day and the lighting mimicked day and night. It held as many as 20 frog including red eyed tree frogs, cuban tree frogs and green tree frogs. There were both geckos and chameleons. It also had a stream and fish pond. In it I witnessed frog, lizard and, most interestingly, slug sex. All this in a one bedroom apartment. I finally sold it on eBay a few years ago.

They will emit a stress call whenever they are in danger, such as when predators are close or when a person steps on a log in which a frog resides.
