Survival at stake: London Zoo seeks female mate for almost-extinct fish; only males known
{{#rendered}} {{/rendered}}The London Zoo is urgently seeking a female mate for the last-known males of a critically endangered fish species.
Zoo officials say the Mangarahara cichlid is thought to be extinct in the wild and that two of the last known individuals — both male — are in the zoo's aquarium. A third is in the Berlin zoo.
Officials say the species' habitat in Madagascar has dried up due to dam construction.
{{#rendered}} {{/rendered}}The zoo on Friday asked aquarium owners and fish collectors to come forward it they know of any living females "so that a vital conservation breeding program can be started."
Officials say a worldwide search of zoo and aquarium organizations has so far proved fruitless.
