Zoo seeks mate for last surviving 'gorgeously ugly' fish

London Zoo is appealing to fish keepers to try to find a mate for a critically endangered, tropical species.
The Mangarahara cichlid is extinct in the wild but the three in captivity are all male.
The Zoo, which describes the fish as "gorgeously ugly", is hoping to start a conservation programme if a fit female can be found for the captive males.
And with two of the males now 12 years old, the quest is said to be extremely urgent.
I think there's probably a very slim to no chance of this fish surviving

These cichlids were named after the Mangarahara river in Madagascar where they were first found.
The construction of dams on the river caused the streams they lived in to dry up and the fish is now believed to be extinct in its natural habitat.
