Big fish eat small fish. Is this true? How would you like to try this out in the Stabfish.io game? The game is a crazy io game. In this game set in the depths of the sea, you have to grow by hunting other fish. As with the swordfish, your fish has a sword in its nose and you have to poke it with other rivals. When the enemy approaches the fish, speed up and make your move. In Stabfish.io Unblocked, you have to watch your back. When there is a fish speeding towards you, speed up and run away. Where there are no rival fish, keep eating plankton and meat pieces left by caught fish. This will give you strength and speed. Thus, you will be the strongest and fastest fish in Stabfish.io game. Take a deep breath and start the game. Achievements.
