Evidence of facultative corallivory is documented in three species of obligate coral‐dwelling gobies (genus Gobiodon ) based on the presence of spirocysts in gut contents. Coral‐dwelling gobies also consumed a broad range of other items with gut contents dominated by algae, invertebrates and amorphous material. Dietary similarities between species suggest corallivory may be widespread in this genus.
