Yes and no. Answers to that question depend on several factors. However, for one example of why you should not allow a breeding pair of cichlids to have multiple broods in the same tank, look no further than Julidochromis dickfeldi. Many species of cichlids can get along just fine with multiple generations of their own offspring, especially shell dwelling species. However, some adults cichlid pairs consider an older brood a threat to the newest brood and will treat the older brood(s) accordingly.
