Title Alternative
Zebrafish swim left to right and prefer an inverted triangle rather than a circle innately without perceptual learning

Abstract
The following results were obtained thorough induction and deduction by four experiments on the early experience controlled zebrafish 4 males and 4 females using 30-30-40 milliseconds behavior analysis system. [1] It was found zebrafish perform two kind of movement. The first is high speed anticlockwise (L→R) spiral circular swimming usig right hemisphere⇔left -visual field. The second is relatively slowly clock (L←R) willing large elliptic swimming usig left hemisphere⇔right-visual field. If we observe from the front of the tank, as DNA they almost always swim L→R basing probably on the rotation and revolution of the earth (Experiment 1). [2] In spite of the innate L→R swimming tendency, zebrafish prefer the visual black inverted triangle side presented to the circle with the same peripheral length. They avoid circle and go to the triangle in group following the leader without perceptual learning irrespective of the position (Experiment 1,2,3,4)。 [3] In such a way, an inverted triangle and a circle are psychophysiologically quite different geometrical configurations.
