Tree cave frogs do not migrate into the water to reproduce like other frogs: they mate and even lay their eggs in trees. The mating season is year-round. After mating, the females lay about 2000 eggs in leaves and flowers filled with water. After just one day, the tadpoles hatch. As with other frogs, they first breathe using their gills, which can be seen on the outside of their heads.

The metamorphosis, i.e. the transformation into a young frog, takes about three weeks. Only then do they have lungs, four legs, and the typical frog shape. The young frogs have a slightly higher contrast than the adult animals: the broad white transverse bands and spots can be seen much more clearly than in the older animals.

Keeping tree-cave tree frogs

Tree cave frogs can be kept in the terrarium. But you need a high rainforest terrarium with the right warm and humid climate with temperatures of 25 to 32 degrees Celsius. Also, they need sufficient plants and branches to have many opportunities for climbing.

When keeping them, you have to keep in mind that the animals need a dry season between June and December – as in their tropical homeland. Then the humidity may only be 60 to 70 percent, while the rest of the time it must be 80 to 95 percent.
