There is a small fish in each box, with various colors such as green, blue, black, purple and variegated, just like wearing a bright "T-shirt". Their "eyes" are also very "delicate", with small mouths, short chins, and big eyes; when not swimming, their bodies are flat. When swimming, its tail looks like an unfurled flag, which is particularly beautiful.
Colleagues told me that this is Thai Douyu . To be honest, this little fish looks quite attractive. I really can’t see how ferocious it is. Why is it called a fighting fish? ! Colleagues said that in fact, Thai fighting fish are famous for their aggressiveness. When two males meet, they will definitely have a duel. Once the "fight" starts, they will become extremely fierce and the winner must be decided. However, when fighting, they will open their gill covers and shake their fins, which is very beautiful and especially suitable as ornamental fish. However, in order to prevent them from fighting, the male fish is usually stored separately, and the two female fish will be in peace if they are put into the same box.
What a magical world, magical fish.
