Convict cichlid fry prefer the more maternally active of two parental females

Article Abstract:

The parental behavior of female convict cichlids and attraction of 2-day-old fry was explored. Results showed that convict cichlid fry tend to spend more time with females who exhibit typical parental behavior patterns. This protects the fry from predators when separated from their natural parents. A female convict cichlid confined farther away from the fry also show more active maternal behavior such as median fins and darkened pelvin fins fully spread with frequent turns toward the fry.

Changes in offspring vulnerability account for the increase in convict cichlid defensive behaviour with brood age: evidence for the nest crypsis hypothesis

Article Abstract:

A study has been conducted to examine the factors that determine parental defensive behavior in the cichlid, Cichlasoma nigrofasciatum, during the different stages of development. The results coincided with the assumptions of the nest crypsis hypothesis, which propose that parental defensive behaviour increases with the vulnerability of the offspring. This suggests that parental defensive behaviour is at its greatest during the earliest stage of development and declines with brood age.

Parental state and offspring recognition in the biparental cichlid fish Pelvicachromis pulcher

Article Abstract:

A study was conducted on Pelvicachromis pulcher alloparental care. Alien conspecific young were accepted by the biparental West African cichlid in their brood if they were of the same age of the adults' young. Those who were not accepted, young which were older or younger than those in the brood, were consumed by the adults. Parents who were separated from their young for over four days consumed their young.
