In effort to learn with an easier animal, I started with a RETF (Red Eyed Tree Frog) before setting up the Poison Dart Frog (PDF) vivarium.
I picked up a single adult (aprox 6yrs old) male from a local guy. It included the established vivarium and a couple cricket keepers. I rescaped the tank, replacing the substrate, adding a false bottom and the foam back wall. I added a cork tube water feature and new plants.
They are relativly easy to keep as compared to the mixed reef tank. Feeding the crickets, feeding crickets to the frogs and misting the plants/frogs, and changing the water weekly.
