This damselfish lives in shallow waters of the Pacific and Indian Oceans. It feeds on algae and small invertebrates, and is recognized by its 5 black vertical stripes and the fluorescent yellow band under its dorsal fin.

Commonly known as the spiny chromis, this damselfish is found in the western part of the Pacific, from the Philippines to Northeastern Australia and New Caledonia. Inhabiting coral reefs up to 65 meters deep, these fish form territorial pairs during reproduction and actively guard the eggs until hatching.

Easily recognizable by its horizontal black and blue stripes on a yellow background, this surgeonfish is a compulsive swimmer. Large males control well-defined feeding territories and surround themselves with a harem of females.

The chocolate surgeonfish, A. pyroferus, gets its name from its color gradient. In addition to this morphological characteristic, this typically solitary species in adulthood is known for its lively and bold nature.

The convict surgeonfish are common inhabitants of the lagoons and seagrass beds of the Indo-Pacific region. Fond of filamentous algae, these herbivorous fish are often found in mangroves and estuaries, at the edge of freshwater. They are easily recognizable by their vertical black stripes.

With an adult size that can exceed 70 cm, the yellowfin surgeonfish is one of the largest fish in its family. This species is found from the coasts of East Africa to the Galápagos Islands. It mainly feeds on diatoms, algae that make up plankton.

The spotted eagle ray, also known as the leopard ray, inhabits coastal and estuaries waters of the Indo-Pacific zone. The largest individuals can reach over 3 meters. Subjected to overfishing, this species, characterized by its gregarious lifestyle and low fecundity, is threatened throughout its range. Partial protective measures exist today in some areas, such as the Maldives and Australia.

Clark's anemonefish is found in a large part of the Indo-Pacific region, going by over a dozen names depending on the region. Capable of living in numerous species of anemone, it is the least picky anemonefish in terms of hosts.

Unlike its famous cousin from the movie Finding Nemo, this tomato clownfish is reddish with a darker body. It has a single white vertical stripe just behind the eye. Young individuals have one to two additional stripes which they lose as they grow.

It is found between 30 and 200 meters deep. It lives near cavities where it takes refuge in case of danger. The male has large pectoral fins and is surrounded by a harem of a dozen females. If it dies, the dominant female becomes a male (protogynous hermaphroditism).

Fertilization is internal. The male uses its anal fin to fertilize the female. The latter deposits a packet of eggs that the male will keep in the mouth until hatching. During the period, it does not eat and can starve to death if it has not accumulated enough reserves.

The arapaima, a freshwater giant reaching sizes of up to 4.5 meters, plays a vital role as a dominant predator in the Amazon basin. Equipped with thick and resilient scales that provide effective protection against predators, this iconic freshwater fish is threatened by overfishing. Juveniles breathe through their gills while adults often use their swim bladder to gulp air at the surface.

It must be kept in a good sized aquarium with efficient filtration, as it is used to chewing it food and scattering it. It is sometimes aggressive toward other species. It breeds easily in captivity. There are several varieties.

The blacktip reef shark is viviparous and gestation lasts about a year. The litter varies from 2 to 4 juveniles, measuring about 40 centimeters. After giving birth, the female abandons it juveniles. If disturbed, this small sized shark, may attack. It gets into the Mediterranean more and more often via the Suez Canal.
