If wetness is the property of having water on something, what is the property of something in water?

I’m firmly on the side of “water is not wet” in this debate, but it’s a question that I was asked while I was high and have no answer to it. Water cannot itself be wet because you can’t get water on water. However, what is a fish in a lake? It can’t be wet until it’s taken out of the water, but it’s not dry...
