who owns the fish?

I have taken some considerable time to find the answer for this, but cannot check it. This problem is from this website, but I can't find the answer in past forums.

Perhapse someone else remembers it, or could figure it out much faster.

----
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.

Re: who owns the fish?

yes, it's the german. it took a lot of time to solve it.
the steps is to put the probabilities by the color of the house, for eg:
we know that the blue house is always the second house and that the green is left to the white so the probabilities are:
Y B G W R
R B G W Y
Y B R G W
R B Y G W

the first 2 options are rejected because the middle house drinks milk and the green drinks coffe
the 4th option rejected because the norwigan is the 1st and the red is brit and so on.......
