How would a fish swim if their was no gravity?
Further more would it need to be completely enclosed so it would remain in the water? or else the water would just float away right?

Not necessarily. Gravity isn't the force that keeps things down but instead the force that brings objects together. So if no force acted upon the water then the water would not move or in this case float away. Also water has an amazing ability to bond to itself. You can fit about 70 drops of water onto a penny if done right so even if there were a force, such as a fish moving through the water, it doesn't mean the water will float away because it may "stick" to the other water molecules.
So to answer your question, a fish would swim normally because for every action (a fish moving its fins/tail back and forth) there is an equal and opposite reaction (the fish moving)
