For long-term space habitation it will help to have a lot of shielding against radiation, and water is a leading option for that.

And it looks like fish do well in microgravity.

And they taste good. So maybe fish will beat birds to space habitats and astronauts will live in a hollow inside of large aquariums.

    Though those fish weren't bred in space it seems. The quails at least hatched from eggs. They had increased rates of deformity. The big question is how humans born on Mars (38% of Earth gravity) would fare.
