I was writing a short note for my great-grand-daughter about my fish as she is interested and came across this!

NASA have doing various studies of fish in space including using Zebra Danio's (Danio rerio) for 45 days and before Japanese rice fish (Oryzias latipes) in 2012 were in space for 60 days.

All to do with bone and muscle studies, as well as an aquarium in microgravity and there was some talk of trying breed Ricefish onboard the ISS.

how do they know which way up too swim?

From footage I've seen they were swimming up the right way but they seem to be struggling in the water.
