Cry no.
However marine fish constantly drink water to maintain a proper osmotic balance where as freshwater fish absorb water instead.
For more information about this, here is an interesting article about how fish drink and osmotic function:

Fish continually drink water--as with most animals, water is necessary to deal with excess nitrogen, and since fish have ample access to water, they just continually drink it in and use it to filter waste out as ammonia.
As for tears, there has been no tear film found on fish eyes. Instead, they have mucus glands in their skin that secrete a protective layer that helps with immune defense and aids in movement through water.

Well, fish have no reason to cry. And obviously they need to drink water, it's essential for all living things.

They don't cry or produce any type of tears.
Freshwater fish do not drink and saltwater fish drink constantly.
