Mixed‐species fish shoals are common, and form for a variety of reasons. We suggest that short term mixed‐species shoals, that persist for minutes or hours, might form because lone individuals (or small groups) of one species might benefit from joining larger groups of heterospecifics to reduce predation risk. We carried out a literature survey, which revealed that mixed‐species groups seldom contain
