It may be a pearl gentian (tiger dragon spot)

Pearl gentian, also known as dragon tiger spot or pearl spot, is a carnivorous fish. It is a filial generation which is produced by crossing the female parent () with the female parent () and the female parent () with the female parent (). It is named after its body surface is covered with dark brown spots resembling pearls. In 26, the University of Sabah, Malaysia and its fishery development agency, together with Kinki University, Japan, successfully cultivated this new species with obvious breeding advantages for the first time by using fish distant hybridization technology.

Gentiana margarita is strong, beautiful and colorful, which looks like tiger spots in its early days. However, in the process of growth, it will gradually shift to the dragon wing, including pectoral fin, ventral fin, dorsal fin and caudal fin resembling the dragon wing, and the patterns and spots on the side of the body are the combination of the two, and the body shape is getting closer and closer to the dragon wing; It has the appearance of tiger-spotted head and dragon-tailed tail, showing the hybrid advantage. Its meat is tender and thick, full of elasticity, without muscle spurs, and it tastes delicious, and its taste is better than that of tiger spots and dragons. The optimum water temperature of this fish is 24-3℃. Because of its hybridization advantage, it inherits the advantages of strong anti-heterosis of tiger spot and fast growth of gentian. It can be cultivated in ponds, cages, factories and other modes. At present, it is the largest artificial breeding and breeding species of grouper in China, accounting for about 7% of the output of grouper.
