Fish are marine creatures found in schools in large water bodies in GTA San Andreas. Fish appear to be 2D sprites rather than 3D models and are non-interactive.
There are various types of fish in the game.
Fish are present in all versions of Grand Theft Auto V including Online. In the enhanced version, fish are one of the animal species the player may experience when consuming a Peyote plant, but only one type, the various other types cannot be controlled.
