What is it about?

When stressed (e.g., when a big predator fish enters the cleaning station), cleanerfish Labroides dimidiatus stop interacting and start "massaging" fish which are being cleaned (clients). We found that increasing serotonin, or blocking a specific dopamine receptor (D1 receptor), disrupts this effect.

Why is it important?

Our findings show that the social strategies of cleanerfish are highly flexible and can be adjusted by the type of fish they are interacting with, and that stress is a part of this puzzle. We also find that the stress pathway does this by interacting with monoamine neurotransmitters.
