Multicolored slices, scientifically known as "pomfret", are tall and flat on one side. If the coat color is good, the gluteal fin is red, there is a wide red stripe in the middle of the caudal fin, and the lateral line of the tail is blue. There is a bright blue band between the dorsal fin and the head. The first fin from the abdomen to the ventral fin has a blue spot behind the cheeks on both sides. The edge of the scale is dark blue, very beautiful and easy to nourish. There are many pictures of thrush on the Internet.
