Relationship between swimming behavior and feeding behavior of juvenile tilapia Oreochromis niloticus fed on water flea Moina macrocopa were investigated under microgravity. The fish controlled their posture with dorsal light response and voluntary fed the water flea under visible light, while the fish could not feed when it showed abnormal swimming in the conditions irradiated near infrared light. In the infrared light, two types of abnormal swimming i.e., looping and rolling were observed and strain difference was confirmed in the pattern of abnormal swimming.
