Can you actually take a bath on the moon, or someplace with a similar gravity? Would you just sit on the top of the water and only get your bum wet? Also, could fish swim or would they just flop around on top? Zero gravity in a sealed container, fish should swim, but how about in low gravity with earth level mass?

Not in the moon, but if you're in a body with a gravity so low that your weight is less than the superficial tension of the water, then yes, you can walk on water. Moon has certainly much more gravity than that, so the only effect you can notice is that you sink a little less than in earth.

Bouyancy has to do with density. Any amount of gravity is enough. So, yes you could take a bath and the fish could swim. But...you, the fish, and the water would all weigh 1/6 of what you weigh on earth. So, if you make a splash, it's going to go everywhere.
To actually take a bath or let your fish go for a swim on the moon, the water would also have to be inside a shelter that is temperature controlled and pressurized. If the bathtub was just sitting out on the surface, you would have problems. Temperatures on the dark side of the moon are colder than -150C. So, the water would quickly freeze solid. Temperatures on the light side of the moon are over 100C, so your bathwater would quickly boil away into vapor. Liquids at low atmospheric pressures boil more easily too, so without your pressurized shelter the water would actually boil and turn into gas at room temperature.

Its all about buoyancy. As gravity pulls an object down, the water it displaces want to fill the void the object created, so it pushes back up. In a low gravity environment, an object that may sink on earth could very well float on the moon. Since the force pulling the object down is significantly less, but the volume of the object has not changed, the resulting upwards force would be greater.
A person on the other hand would still sink to the bottom of a normal sized bath. You may sink a little slower, but the gravity on the moon vs. earth (about 1/6) would still be strong enough to allow you to be squeaky clean.

Of course you could take a bath, it's low gravity, not zero gravity. Not only could you take a bath, but fish could swim, so could you, actually using less energy. also you could take a shower, albeit the water would fall slower or more gently as the case may be.

If the gravity is great enough to keep the water from splashing away, then anything denser than water on earth is still denser than water in the lower gravity field. Ergo, you can take a bath, and fish will remain in the water.

It seems to me that buoyancy should not change with gravity. As long as there is some gravity I would expect you to sink or float just like on Earth.

The moon does not have zero gravity.
Bouyancy is a function of density, and relative densities are preserved in lower gravity systems.

yes, you can! the situations such as gravity and environment are sufficient. provided you bring your own oxygen and water supply, it'll work.
but it would be a waste of resources to bring all those there just to take a bath.
Hope this helps, Peace.

no because there isn,t much water on the moon.
