The swimming behaviour of adult and neonate swordtail fish Xiphophorus helleri was qualitatively analysed from video recordings taken throughout the STS 89 spaceshuttle mission from launch to landing and thereafter. After the flight, the swimming behaviour of neonate samples was quantitatively assessed in the course of the readaptation to 1g earth gravity at days 0, 1 and 4 after recovery. Regarding the swimming behaviour during the mission, the adult fish swam thigmotactically (i.e., responding to tactile stimuli) along the walls of their aquarium, but like the neonates, they did not show any aberrant behavioural patterns. This indicates that they could easily adapt themselves to microgravity. On mission day 9, however, looping responses (most probably initiated by mechanical disturbances) occurred indicating a continuously performed "C-start" escape response (the respective body bend looks like the letter "C"). Immediately after landing (observed in videos recorded onboard the space shuttle), the adults performed a head-up swimming beating heavily with the caudal and pectoral fins; this aberrant behaviour gradually decreased during the first hours after recovery.
