In the predator and scavenger abundant waters of Indonesia, Banggai cardinalfish – masters of parenthood – work to keep their offspring alive.
Rather than laying her eggs amongst plants or crevices, a female Banggai’s chosen partner is quick to snatch them up in his mouth. During 30 days of comfy mouth residence, the eggs rapidly develop into miniaturised forms of their parents. The male gets no food during this trial, but is supported through the starvation by the fierce defence of his partner, and the knowledge that soon his tiny offspring will be ready to face the world themselves (from the comfort of a nearby anemone).
The Banggai cardinalfish is classified as Endangered by the IUCN, due to overcollection from the wild to meet the demands of the pet trade.
