Fun facts
Shared with the species: Jack Dempsey Cichlid
The 'Electric Blue Jack Dempsey' is a natural recessive color mutation (not a hybrid) where reduced dark pigmentation reveals brilliant electric-blue iridescence. Because the mutation is recessive, breeding for it is challenging. Named after Jack Dempsey, world heavyweight champion 1919–1926.
