Abstract
WHEN a minnow (Phoxinus phoxinus L.) is allowed to swim freely on an illuminated white or black background, it becomes correspondingly pale or dark in colour and remains so indefinitely. However, if the fish is kept stationary by confining it on a white or black background in a glass tube containing running aerated water, its colour responses become abnormal1.
