Are there fishes that can survive in both fresh and salt water?
And can they spend their whole lifetime in any of the environment or its just temporary survival?

Yes, but it's an unusual characteristic.
Re: your update -
For some, it varies with their life cycle. Fresh at one point, salt at another. Like with most species of salmon. This is the most common type.
For others, they can move back and forth at will. Which is much less common.

Sockeye salmon and bull sharks both can. I’m sure there are also others I’m not aware of.
