Declared extinct in the wild in 2003, species has been reintroduced to its native river after being bred in Chester
A “charismatic little fish” declared extinct in the wild has been reintroduced to its native Mexico after being bred in an aquarium at Chester zoo.
The tequila fish (Zoogoneticus tequila), which grows to no bigger than 70mm long, disappeared from the wild in 2003 owing to the introduction of invasive, exotic fish species and water pollution.
