Who Owns The Fish?

This is my favorite puzzle.

There are five houses in a row and in five different colours.
In each house lives a person from a different country.

Each person drinks a certain drink, plays a certain sport, and keeps a certain pet.

No two people drink the same drink, play the same sport, or keep the same pet.

* The Brit lives in a red house
* The Swede keeps dogs
* The Dane drinks tea
* The green house is on the left of the white house
* The green house owner drinks coffee
* The person who plays polo rears birds
* The owner of the yellow house plays hockey
* The man living in the house right in the centre drinks milk
* The Norwegian lives in the first house
* The man who plays baseball lives next to the man who keeps cats
* The man who keeps horses lives next to the one who plays hockey
* The man who plays billiards drinks beer
* The German plays soccer
* The Norwegian lives next to the blue house
* The man who plays baseball has a neighbour who drinks water.

So, who owns the fish?
