There is more water on the outside of the fish than on the inside. So the water will enter the fish's cells, causing no change in the cells' size.
There is more water on the inside of the fish than on the outside. So the water will leave the fish's cells, causing them to shrink and die.
The amount of water is the same throughout the fish's cells and the tank, so nothing will happen.
