Nusa Penida - List of fishes

The blacklip butterflyfish has a broad geographical distribution that spans from the Red Sea to the Galápagos Islands. Typically, it is found alone or in pairs in shallow coral reefs. It feeds on polyps of soft corals, particularly leather corals and broccoli corals.

The blue-green Chromis is a fish that lives in large schools above dense coral areas. At the slightest alarm, this swift fish takes refuge in the colonies of branching corals. The Blue-green Chromis is common throughout the Indo-Pacific region.

The Coral Hawkfish most often rests in or under the corals to ambush its prey, mainly crustaceans and small fish. In this species, territorial males form a harem of females. Reproduction occurs in the water column, with eggs and larvae developing in ocean currents and becoming part of the zooplankton.

The African clown wrasse, or Coris gaimard, is a solitary fish that changes color throughout its life, transitioning from orange with black and white eye spots in juveniles to a multicolored pattern in adults. Females turn into males, recognizable by the large green lines on their head. This species mainly feeds on mollusks, crabs, and hermit crabs and primarily resides in reefs.

Ctenochaetus striatus, elegantly named the "striated surgeonfish", is found in the tropical waters of the Indo-Pacific, particularly in the lagoons of La Réunion and Mauritius. In Tahiti, during the full moon, this fish displays a natural spectacle: large schools form, and after a brief moment of stillness, each individual breaks away to release eggs or sperm.

The whitetail Dascyllus resides in the tropical waters of the Indo-Pacific region and the Red Sea. This white reef fish striped with three black bands is often found in large groups above massive colonies of staghorn corals. It feeds on zooplankton, benthic invertebrates, and algae. During the breeding season, males choose the nest and perform a dance just above it as a courtship display. The female is then invited and escorted to the nest where spawning takes place.

The common name of this species refers to the patterns observed in young individuals. Adults typically live among the arms of branching corals, while juveniles more often reside among the tentacles of anemones. These fish are omnivores with a carnivorous tendency.

The long-spine porcupinefish is a pufferfish found in the majority of tropical and subtropical marine areas around the globe. Juveniles can be found in small groups. As they age, this species becomes more solitary. Specialized in hunting mollusks and small crustaceans, this fish exhibits a seemingly clumsy swimming behavior.

The dorsal fin of the fish, turned into suction cup allows it to cling to other animals. It sticks mostly to the body of the animal, but also in the mouth or near the gills of some "hosts" (mantas, sharks ...). it often eats its host food leftovers.

This butterflyfish is easily recognized by its elongated snout, which is useful for capturing aquatic microorganisms among corals. It also uses it to peck at the feet of echinoderms, the pedicellariae of sea urchins, and the tentacles of marine worms.

In some languages, this fish is called the "birdmouth wrasse" because of its hopping swimming, its long pectoral fins and a long "nose". It is hermaphrodite and changes sex and color in it life. Juveniles and females have two colors, while males are blue.

The checkerboard wrasse inhabits the slopes and sandy expanses of lagoons and coral reefs. Its diet primarily consists of prey with tough shells. It can be observed at depths of up to around 30 meters
