There are 5 houses in 5 different colors. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.
The question is: Who owns the fish?
Hints:
The Brit lives in the red house.
The Swede keeps dogs as pets.
The Dane drinks tea.
The green house is on the left of the white house.
The green homeowner drinks coffee.
The person who smokes Pall Mall rears birds.
The owner of the yellow house smokes Dunhill.
The man living in the center house drinks milk.
The Norwegian lives in the first house.
The man who smokes Blend lives next to the one who keeps cats.
The man who keeps the horse lives next to the man who smokes Dunhill.
The owner who smokes Bluemaster drinks beer.
The German smokes prince.
The Norwegian lives next to the blue house.
The man who smokes Blend has a neighbor who drinks water.
Einstein is credited with writing this riddle early during the 19th century. He said 98% of the world could not solve it. Its not hard, you just need to pay attention and be patient.
No fair looking up the answer.

Fish isn’t mentioned so can’t answer the question OR based on just the info provided the answer is none. (And if you’re able to eliminate 4 of the guys who have pet X, leaving only one left, that doesn’t mean the one remaining owns fish. he might own turtles or worms for all we’re told. 
)
Fun, but I doubt very much Einstein came up with this, though saying he did adds to the impression that the riddle must be extremely difficult.
I love these things and I did this one (and several others like it) years ago. It’s solvable and doesn’t require anything more than time, pencil, and paper.

It's solvable and doesn't require anything more than time, pencil, and paper. :)I'm not so sure. i took a crack at it and I think there is not enough information given to figure it out. I could go only so far before running into a blind alley with nowhere to go. Maybe Einstein was trying to teach a lesson about proceeding with a lack of crucial information. Lois
