Aquarium du Limousin

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 skeleton of this sturgeon is made of cartilage. it barbs, on the front of it mouth, allow it to search for food in the sand. As it is the case for the larger species (beluga, Sevruga ...), its eggs are used for the production of caviar.

It easily accommodates to life in captivity, but it is aggressive toward smaller species. It breeds easily in aquarium: the male delineates a territory in which the female lays its eggs. After hatching, the pair will protect juveniles against potential predators.

It owes its name of "freshwater shark" only to the shape of its dorsal fin. It behavior and it food have nothing comparable. It acclimates easily to the aquarium.

Small barbs located around its mouth enable it to detect food. It is easy to breed in captivity. The species is very prolific, nests often have over 500 juveniles.

The female has a broader abdomen than the male. To escape predators, it can make impressive leaps out of the water and "fly" by using its pectoral fins. That is why it is recommended to keep it in a covered aquarium.

The coral beauty angelfish is always born female. As they grow, individuals change their sex to become male, a phenomenon known as protogynous sequential hermaphroditism. The difference between male and female is therefore visible. The adult male is larger and has an anal fin ending in a point.
