IQ test

Today I decided to post a little test hoping that we'll have some fun. It's called "Einstein IQ test". I admit I have done this test and it can be fun or not. It depends of the state of mind. First of all I'll ask you not to cheat and look on the internet for the answer. So what we are waiting for? Let's get started!

There are 4 facts:

1) There are 5 houses in 5 different colors.
2) In each house lives a person with a different nationality.
3) These 5 owners drink a certain beverage, smoke a certain brand of cigar, and keep a certain pet.
4) No owners have the same pet, smoke the same brand of cigar or drink the same drink.

Hints:

1) The Brit lives on a red house.
2) The Swede keeps dogs as pets.
3) The Dane drinks tea.
4) The green house is on the left of the white house.
5) The green house owner drinks coffee.
6) The person who smoke Pall Mall rears birds.
7) The owner of the yellow house smokes Dunhill.
8) The man living in the house right in center drinks milk.
9) The Norwegian lives in the first house.
10) The man who smokes Blend lives next to the one who keeps cats.
11) The man who keeps horses lives next to the man who smokes Dunhill.
12) The owner who smokes Blue Master drinks beer.
13) The German smokes Prince.
14) The Norwegian lives next to the blue house.
15) The man who smokes Blends has a neighbor  who drinks water.

The big question is: Who is the keeper of the fish?
