Animal behaviour: Trust in fish

Lee Alan Dugatkin1

A mutually beneficial interaction between two species of fish turns out to involve the careful appraisal of one by the other — and the appropriately virtuous behaviour by the former while being watched.

Many animals, including humans, are scorekeepers, paying close attention to what others do to them and responding in kind. This sort of tit-for-tat reciprocity works well, but is limited to instances involving some sort of direct, one-on-one, interaction.
