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. 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.
In GTA Online fish are only present in the Pacific in the enhanced version of the game.
