What is it about?
Social interactions are both a source of stress and a relief from it. Interestingly, many of the brain regiona that have been implicated in stress are also associated with sociality. This paper examines the relationship between stress and sociality in fish, the most diverse group of animals on Planet Earth, and the association of both with neurotransmitters such as dopamine and serotonin.

Why is it important?
Shared brain pathways for sociality, stress, and reward represent important neurobiological facts in the life of fishes. Fish are increasingly being used as model organisms in the neurosciences, and so scientists need to incorporate neuroanatomical, behavioral, pharmacological, and ecological studies conducted both in the laboratory and in nature to understand how stress and sociality interact. These approaches could have larger implications for studies involving disorders of stress and social behavior, but also have important evolutionary consequences.
Perspectives
Writing this not only was a joy and a great opportunity for consolidating collaborations, but also a way of delving back into the larger literature on fish physiology and behavior and re-contacting with literature apart from the zebrafish. Ultimately, I hope that people will start to appreciate the intricate relationships between behavioral domains, as well as the usefulness of fish models.
