Red Sea bannerfish (Heniochus intermedius), Red Sea, Egypt. The Red Sea bannerfish attains as maximum total length of 18 centimetres (7.1 in) and is native to the western Indian Ocean where it is found in the Red Sea and the Gulf of Aden. It's associated with coral reefs where it is most frequently recorded as a solitary fish or in pairs, although large schools have been recorded. The juveniles form large schools, particularly in areas of deep reef where there is a low density of corals. They feed on both zooplankton and benthic invertebrates but the extent to which they feed on live coral has still to be determined. It is an oviparous species which forms monogamous pairs for spawning. It's collected for the aquarium trade but its collection is of a limited scale and is not believed to be a threat to the species population.
