Scientists perform fish study in space

Four Zebrafish brought into orbit in China’s space station are in good condition after 20 days. The four fish are now living in a small ‘aquarium’ in the laboratory module on the space station. They were sent to the space station for a life, science and ecological experiment to study how the space environment affects fish’s growth and system balance. The experiment has so far been successful, the scientists have found some abnormal directional behaviours of the Zebrafish, moving in circles and even swimming upside-down.
