“…Once able to effectively swim, fry can more easily escape predation (Wisenden et al. ), and thus, the influence of predation on deserted broods and parental care likely decreases as fry age.…”

“…Here, we take advantage of the unique biparental system to understand how multiple, conflicting tasks influence biparental care. Additionally, we examine this within the context of mate loss, a topic that is widely discussed within the avian literature (Wright & Cuthill ; Whittingham et al. ), although usually only within parents that exhibit a division of labor and not a division of roles.…”

Biparental care of young occurs when both parents provide some sort of care for offspring and can include a wide variety of behaviors, yet often studies focus on single aspects of parental care when trying to determine how each parent contributes. Here, we presented the biparental convict cichlid fish (Amatitlania nigrofasciata) with two conflicting parental behaviors: retrieval of non-swimming offspring that have been displaced from the nest and defense against a conspecific intruder, a potential brood predator. We examined single males, single females, and pairs of parents to determine how males and females each contributed to overall parental care. Traditionally in this species, parents exhibit a division of labor (in which each parent contributes to all parental activities), but also exhibit a division of roles (in which males tend to favor the role of defense and females tend to favor more direct care, spending more time with offspring). We hypothesized that single parents would compensate for their absent mate, but that males and females would still favor preferred roles. Additionally, we hypothesized that there would be an asymmetrical expansion of roles, with females being more flexible. Our results show that the preferred roles of both parents were evident even when parents were without their mates and that males and females differed in their compensatory levels, at least when compared to the behaviors of the intact pair. Contrary to our prediction, females seem unable to fully compensate for the defensive behaviors usually exhibited by males, while males shifted completely to retrieve displaced offspring.

Colour production in fish is due mostly to food. In conditions of captivity, the type of food is restricted, while various types of food are used in aquaculture, from processed dry food to small aquatic animals. In this study, we used nauplii of Artemia franciscana, "water fleas" Moina wierzejski, micro-worm Panagrellus redivivus, and commercial flakes. We used Poecilia reticulata, which is one of the most traded fish in ornamental aquaculture and hypothesise that if the live food influences the coloration and growth of P. reticulata, there must be differences in the intensity of colour pattern and growth rate in fish fed with different living animals. Consistent with our prediction, females and males of P. reticulata were more colourful when they were fed on A. franciscana, P. redivivus and M. wierzejski than when they were fed commercial flakes. Females and males of P. reticulata fed with A. franciscana grew in less time than fish fed with P. redivivus, M. wierzejski, or commercial flakes. We conclude that live food is an excellent way to affect growth and coloration in fish.

“…By combining phylogenetic and behavioral analyses, this study infers how and why the unique body coloration, mating system, and parental care behavior in H. mickleyi evolved. Also addressing the evolution of brood care, Wisenden et al (2015) correlate parental brood defense with larval antipredator competence in the convict cichlid Amatitlania siquia. They suggest trait co-evolution driven by interactions between parental care behavior, swimming performance of young, and habitat-specific predation pressure.…”
