Phantom bannerfish
The phantom bannerfish is a reef fish of the family Chaetodontidae from the central Indo-Pacific. The body is deep and strongly flattened; the first dorsal ray is elongated into a "banner". Coloration is light with contrasting dark areas: a "mask" through the eye, a broad dark band behind the head and a dark patch or zone at the tail base; the upper body and back are often yellowish. It lives in coral-rich lagoons and on outer reef slopes, in pairs or groups (sometimes large schools in some areas), often on reef crests in the surge zone.

Phyllidia coelestis
Phyllidia coelestis is a nudibranch (sea slug) of the family Phyllidiidae. The body is oval, up to 6 cm. Coloration is grey-blue with three longitudinal black lines: two on the sides and one in the centre that forms a characteristic Y-shaped pattern in front of the rhinophores. The back is covered with bright yellow tubercles; the rhinophores are usually yellow. By day it crawls actively over the reef and feeds on sponges; the colour is warning coloration, and many phyllidiids are toxic to predators.

Raccoon butterflyfish
The raccoon butterflyfish (lunula) is a reef fish of the family Chaetodontidae, widespread in the tropical waters of the Indian and Pacific Oceans. It is recognised by its "raccoon mask" — a black band through the eye with a white edge — and a black spot on the tail base. The body is oval and strongly flattened; main colour is yellow with white areas and oblique dark reddish or brown streaks on the sides. It is usually seen alone, in pairs or small groups on reefs and in lagoons, and feeds on various invertebrates and sometimes coral polyps.

Redtail butterflyfish
The redtail butterflyfish (also known as the Pakistani butterflyfish or collare butterflyfish) is a reef fish of the family Chaetodontidae from the Indo-West Pacific. It has a deep body and short snout; coloration is brownish-olive with a "netted" pattern (pale scale centres and dark edges). The head is dark with white marks near the snout and a broad white vertical band behind the eye ("collar"); the tail fin is bright red or orange-red. It is usually seen in pairs or small groups on the reef edge and upper slope, and feeds on coral polyps and other invertebrates.

Dusky parrotfish
The dusky parrotfish (Scarus niger) is a reef fish of the family Scaridae, found across the Indo-Pacific region including the Red Sea. It has a typical parrotfish "beak" of fused teeth used to scrape algae. Coloration varies greatly with age and sex and may include shades of blue, green, purple and almost black; it is often seen alone. It feeds mainly on benthic algae on hard substrate and dead coral, grazing actively on the reef by day.
