So the cartoon… I mean, the highly technical diagram in yesterday’s post implied that being in space wouldn’t be much of a thrill for fish. I mean, they swim up, they swim down… they swim in whatever direction they want, right?
But then I found a video showing a side-by-side comparison of the fish tank aboard the International Space Station and an identical fish tank down here on Earth, and it looks like I was very, very wrong. Fish do change their swimming behavior in microgravity. It’s really pretty, actually, watching them spin and twirl about.
