This study aimed to assess the feeding association between coral reef fishes and the hydrozoan Millepora spp. in two different reef systems (Tamandaré reefs and Fernando de Noronha archipelago) of Pernambuco State (north-eastern Brazil). A total of eight reef fish species, predominantly juveniles, were recorded feeding on colonies of Millepora spp. during 35 records. The highest recorded feeding rate was 1.72 ± 0.87 bites.minute-1 for Sparisoma axillare and the lowest was 0.18 ± 0.40 bites.minute-1 for Stegastes rocasensis. The colony structure of the genus Millepora supports a high diversity of microfaunal and macrofaunal invertebrates, which may result in the frequent foraging behaviour observed here.
