“…These ଏsh commonly live in stable social groups with repeated interactions and show highly developed behavioural responses to encounters with mates, social partners, rivals, and competitors, including heterospeciଏcs (Taborsky 1984;Martin and Taborsky 1997;Balshine-Earn et al 1998). In addition, the cichlids also have highly developed socio-cognitive abilities, including memory of past social interactions, facial and kin recognition, and commodity trading (see Félix and Oliveira 2021). Almost every aspect of the interaction between cichlid ଏshes consists of a wonderful array of postures, colour changes, ଏn movements, and reciprocal behaviours.…”

“…The mechanisms underlying this behavioural transition are well understood, particularly in the African riverine mouthbrooder A. burtoni, where social status changes are associated with a range of gene expression, endocrine, and morphological shifts. The details of the mechanisms underlying these social changes are discussed by Félix and Oliveira (2021).…”

“…In addition to studies of cognition, cichlids are emerging as a prime system in which to study the structure and function of brain regions associated with social interactions across vertebrate species (O'Connell et al 2011;Félix and Oliveira 2021). Within the vertebrate brain, two neural circuits are most commonly examined in studies of social behaviour-the Social Behaviour Network (SBN; Goodson 2005;Newman 1999) and the mesolimbic reward system.…”

The complex social behaviour of cichlids has fascinated scientists and hobbyists alike for almost 100 years. In this chapter, we review the breadth and complexity of cichlid behaviour, particularly with respect to social interactions. We present the case that cichlids are one of the best model systems for understanding both the mechanisms and evolution of behaviour. This is due to the fact that cichlids can be observed without being greatly disturbed, both in the aquarium and ଏeld and because of the unique opportunity to experimentally manipulate their environment and behaviour. We ଏrst give a brief account of the diversity of social systems in the cichlids and the diverse research in this area, from the very early work of authors like Curtis, Noble, and Baerends, to modern studies into the dynamics and structure of social behaviour in these ଏsh. In Sect. 2, we explore the causal factors leading to the evolution of social complexity, discussing the occurrence and evolution of different social systems across ecological and life-history contexts. We investigate the behavioural complexity displayed by cichlids in Sect. 3, including a brief treatment of the different modalities of behavioural interactions. In Sect. 4, we discuss the immense potential for using cichlids as model species in studying social and behavioural evolution, before ending in Sect. 5 with exciting future directions for research employing the latest technical advances in both the laboratory and ଏeld.

“…Secondly, the social cognitive demands modulating brain size differences manifest more broadly in the brain rather than in the forebrain alone. While this concept is supported by a growing body of literature (discussed in Félix andOliveira, 2021 andKelly, 2022), we note that it cannot explain the differences between batu coris and cleaners. Thirdly, it has been pointed out in interspecies comparisons that brain size often correlates best with the amount of sensory information processed and the precision of motor control that a species possesses (van Schaik et al 2023).…”

The factors shaping brain evolution and cognition are broadly categorized as being either social or environmental. However, the relative importance of these factors is heavily debated, partly due to the limitations from the standard interspecific evolutionary comparative approach. Here, we adopt a complementary strategy leveraging the high degree of brain plasticity that evolved in fishes to ask how variation in social and environmental factors affect individual brain development. We investigated how overall brain size and brain part sizes varied between demes of the same population in the coral reef associated batu coris Coris batuensis. This wrasse species is ideal for our approach because its local population densities (a correlate of intraspecific social complexity) are dissociated from both densities of other species (reflecting interspecific complexity, including competitors and predators) and habitat complexity (represented by the three-dimensional structure of the coral reefs and adjacent areas). We found that individuals from demes with higher intraspecific population density possess larger overall brain volumes than those from lower population density environment, caused by an enlargement of all five main brain regions. Brain anatomical measures did not correlate with measures of interspecific or habitat complexity. Our results suggest that brain plasticity in the batu coris evolved to allow individuals to adapt specifically to variation in intraspecific social challenges. The results support a broader version of the social brain hypothesis, emphasizing the entire brain over specific regions like the neocortex in mammals or the telencephalon in fishes.

“…The huge variety of teleost species provides flexibility in choosing appropriate fish models to investigate specific parameters or characteristics. For instance, highly socialized fish such as cichlid and salmonid fish are most suitable to be used as a model for social stress study ( Gilmour et al, 2005 ; Félix and Oliveira, 2021 ). An advantage of fish models in social stress study as compared to typical rodent models is that the stress response in fish is found to be similar to humans where fish also secrete cortisol when stressed ( Barton, 2002 ).…”

Stress is an important aspect of our everyday life and exposure to it is an unavoidable occurrence. In humans, this can come in the form of social stress or physical stress from an injury. Studies in animal models have helped researchers to understand the body’s adaptive response to stress in human. Notably, the use of behavioural tests in animal models plays a pivotal role in understanding the neural, endocrine and behavioural changes induced by social stress. Under socially stressed conditions, behavioural parameters are often measured physiological and molecular parameters as changes in behaviour are direct responses to stress and are easily assessed by behavioural tests. Throughout the past few decades, the rodent model has been used as a well-established animal model for stress and behavioural changes. Recently, more attention has been drawn towards using fish as an animal model. Common fish models such as zebrafish, medaka, and African cichlids have the advantage of a higher rate of reproduction, easier handling techniques, sociability and most importantly, share evolutionary conserved genetic make-up, neural circuitry, neuropeptide molecular structure and function with mammalian species. In fact, some fish species exhibit a clear diurnal or seasonal rhythmicity in their stress response, similar to humans, as opposed to rodents. Various social stress models have been established in fish including but not limited to chronic social defeat stress, social stress avoidance, and social stress-related decision-making. The huge variety of behavioural patterns in teleost also aids in the study of more behavioural phenotypes than the mammalian species. In this review, we focus on the use of fish models as alternative models to study the effects of stress on different types of behaviours. Finally, fish behavioural tests against the typical mammalian model-based behavioural test are compared and discussed for their viability.
