The Siamese fighting fish (Betta splendens), also sometimes known as the Betta Fish, is a species in the gourami family that is popular as an aquarium fish. They are called pla-kad (fish-biting) in Thai or trey krem in Khmer.

They are very aggressive fish and it is unwise to keep two males together and even females can fight each other. They have poor eyesight and can mistake the betta's tail flowing for worms or prey. Get the cool wallpapers here.
