The activity patterns and substratum selection for foraging of checkered snapper Lutjanus decussatus were observed. The foraging rate of small‐sized individuals (<150 mm in total length, L T ) was significantly greater than that of large‐sized individuals (≥150 mm L T ). There was significant positive use of live branching corals, whereas negative use of coral rubble, rocks and sand for both small‐sized and large‐sized individuals.
