Either is correct. if you say "fish live in water," most English speakers would think you were speaking of fish in general. If you say "fish live in the water," it would be assumed that you were speaking of a particular body of water, as in, "I live near a pond--fish live in the water, but we have no muskrats."
But if the question was "Where do fish live?" either is equally correct.
Sincerely there used to be a study executed over 10 years. Began with two tanks, one salty, one contemporary. Over the course of the 10 years, they diminished the salt in the salty one, and raised the salt within the recent one. At the end of the 10 years, once they have been the same salt stage, they put the fish together, and so they were exceptional.

There is no need for "the" water. The point is taken with just water.
