What is oscar fish?
The oscar fish (scientific name: Astronotus ocellatus) is a species of fish in the cichlid family and the genus tuna. The body length is 33 cm and the maximum weight is about 1.1 kg. The fish is oval in shape, with flat sides, a large head, a large mouth, and broad fin rays. Not only has teeth on its jaw, but also a set of pharyngeal teeth. The teeth in the jaws are small and used for grasping, while the teeth in the throat (pharyngeal teeth) are used to manipulate and handle prey. The base of the dorsal fin is very long, from the back of the corresponding part of the thoracic poison fin to the caudal peduncle. The pelvic fins are thoracic, and the fins are pointed and bar-shaped. The anal fin is symmetrical with the dorsal fin, the fin ends are longer than pointed in males, slightly rounded in females, and the caudal fin is fan-shaped. The body color is black or dark brown, with irregular orange-red patches scattered on the side of the body, with red stripes in between, which is named after the map. There is a circular black spot above the base of the caudal fin, and an orange-red ring around it, which sparkles when swimming, like the stars on a summer night, hence the name “tail star fish”. Mature fish, the large black spots on the tail handle are shaped like eyes, which can be used as a protective color and a lure color, so that other fish cannot distinguish the front and back, and it is easy to become a Chinese food in the mouth of the tuna. Before the tuna has reached sexual maturity, the characteristics of male and female are not obvious, and the sex is not easy to distinguish.
