Description

It is a fish up to 30 cm in adulthood, see more.

It is distinguished in particular by its enormous mouth and its ocelle on the Caudal peduncle, this one even at the origin of the name ocellatus.

In its natural state, its flanks are most often from brown to black, haloed with orange red areas.

However, the forms of breeding generally see these areas sometimes extend uniformly over almost the whole body.

In addition, there are albino forms, of an ivory white and whose sides are copper.

The ocellatus astronotus, also known as Oscar or Oscar with ocelli, is a Cichlid type fish from South America. It is characterized by a variable coloring, but generally orange with black and white spots on the body, as well as by a caudal fin in the shape of a peacock. The Oscars generally measure between 20 and 30 centimeters in length, but can reach up to 40 centimeters in certain situations.

Oscars are very intelligent and curious fish, and they like to interact with their environment and the humans around them. They are also known to be territorial fish, and they can become aggressive towards other fish or aquatic animals if they feel threatened. This is why it is important to keep them in a sufficiently large and well -appointed aquarium to allow them to move freely and exercise their natural instincts.

Oscars are carnivorous fish, and they feed mainly on living prey such as insects, worms and small fish. In the aquarium, they can also be fed with food designed for carnivorous fish, such as pellets or frozen foods. It is important to offer them a varied and balanced diet to allow them to maintain good health and a beautiful color.

Reproduction

Not always easy, because it takes a group of 7 to 8 unptors in hoping that a couple will stand out, because we do not distinguish the male from the female. It is necessary to bring together several favorable points such as: a male and a female (which is difficult to recognize in the Oscars), then there is also a good understanding between the two faden finally they will place their eggs on a flat surface such as a flat stone. We must not worry if the Oscars set off in a violent borderline fight, it will only be a love parade that can be lucky.
