Convict Cichlid vs Jack Dempsey: common questions
Which is easier to breed, the convict cichlid or the Jack Dempsey?
The convict cichlid is considerably easier to breed, considered one of the most prolific cichlids in the aquarium hobby, with a single well-matched pair capable of producing frequent broods under a wide range of conditions, while the Jack Dempsey breeds successfully but with somewhat less ease and frequency.
Does the Jack Dempsey look the same as a juvenile and as an adult?
No, the Jack Dempsey hatches and matures as a drab, plain grey juvenile before gradually developing the iridescent blue-green spangling across a darker body that characterises the adult form, a dramatic transformation the convict cichlid does not undergo to nearly the same degree.
Why is the Jack Dempsey named after a boxer?
The Jack Dempsey was named after heavyweight boxing champion Jack Dempsey as a reference to its notably pugnacious and territorial temperament, a naming convention distinct from the convict cichlid, whose common name instead describes its bold black-and-white prison-stripe pattern.
