Would two pairs of breeding Convicts ( 3 to 4" ) be ok in a 55 gallon for life, the only other fish in there is a small ( 1" ) Jaguar Cichlid. The Jag will only be there on a temp. basis. One pair has already begun digging a nest. How long does it take for them to lay eggs and how often do they have babies? How many babies per nest can I expect? What do other MFK keepers do with the fry?
