Leucomelas are one species within the genus of Dendrobates where the male will carry tadpoles and deposit them into pools of water within the forest. They prefer the cups of Bromeliads, which many poison dart frog keepers provide within their vivariums.

Interestingly enough, Leucomelas tadpoles can be cannibalistic. If a tadpole is deposited into a bromeliad where a tadpole already exists, the larger tadpole will eat the smaller one.
