I've been keeping frogs for quiet a few years now and my collection has grown quite a bit which takes up a whole room. Anyone that keeps Dart frogs knows it's quite an addictive hobby. A lot of the interest is maitaining their enclosures and creating them as similar to their natural environment as possible. They don't need supplimentary heating and comfortable room temperature that doesnt fall below 18c is pefect.  Plants growing in the vivarium are as interesting as the frogs themselves. Seeing how they use the pools in a Bromelaid plant to raise their tadpoles is fascinating and shows me they are happy.
