These frogs have very fascinating reproductive behaviour. After the courtship the male fertilises the eggs and then guards the clutch on his own for about a week, urinating on the developing spawn to keep it moist. After about a week the female returns and carries them one by one to a wee hidden reservoir of water often cavities of bromeliads. Then she is watching the tadpoles, feeding them with her unfertilized eggs. the adult frogs hide in dump cavities under stones etc but once it rains they come out and croak calling for mates.
