|Reaction||Flees when Ecco swims near or hits them with sonar. Small orange schools will flash when hit with sonar.|
In Ecco Junior they serve as an objective in The Fish Caves, where dolphins must herd them with their sonar into either Seahorse cave. In Ecco: Defender of the Future a dolphin in Aquamarine Bay requests that Ecco brings him a red fish.
Schooling fish swim in schools throughout a region of levels. When charged they tend to flee, but soon regain their formation.
