Bcoz the hints doesn't provide any info regarding the fish. So there may be a chance that all the five houses would have fish. I hope this may be the right answer. Isn't it?πNorvicuteALBERT EINSTEIN WROTE THIS RIDDLE EARLY DURING THE 19th CENTURY. HE SAID THAT 98% OF THE WORLD POPULATION WOULD NOT BE ABLE TO SOLVE IT. -

barryn56The German keeps fishes. Construct a 5 by 5 grid and note that each item is mentioned once except for smokes (2 x dunhill and 2 x Blends) and pets (fish missing). As you go through the clues there will come a point where the neighbour can only be one choice, then it is easy...
-
MungutiYeah the german keeps fishπ. It took time but i eventually figured it out. nice riddle.
-
swati_akasheenigerman will keep the fish,this riddle can be solved by creating a table according to the giving conditions and ultimately result comes out to be german.

Kaustubh KatdareOkay, now someone will have to explain the whole decision making process.

AnkitaDeshpanderight.
the ans is GERMAN
but it comes after assumptions... -
gohmNobody owns the fish as ownership denotes material possession which is an illusion and maya. The fish is a free being of the cosmos.
or if you do not like the exostential answer...
the German, laugh. Love this puzzle. -

Take a look at following clues:
1.The British lives in a red house.
4. The Green house is next to, and on the left of the White house.
So color of 1st house cannot be Green,White or Red. So its Yellow.
and from this
7. The owner of the Yellow house smokes Dunhill.
11. The man who keeps horses lives next to the man who smokes Dunhill.

From the next clues:
4. The Green house is next to, and on the left of the White house.
5. The owner of the Green house drinks coffee.
So house number 3 can neither be green nor white. So its red.
and hence house number 4 and 5 are green and white respectively.
Also from
1. The British lives in a red house.Brit lives in house number 3.
5. The owner of the Green house drinks coffee.

Further:
12. The man who smokes Blue Master drinks beer.
3. The Danish drinks tea.
The only drink left for house number 1 is water.

Look at this clue:
12. The man who smokes Blue Master drinks beer.
Now the only house which satisfies this is house number 5
Thus resident of house number-5 drinks beer and smokes BlueMasters and the only drink left behind is Tea.

Last set of clues required::
6. The person who smokes Pall Mall rears birds.
thus Pets in house number 3 are birds.
and with help of this clue:
10. The man who smokes Blends lives next to the one who keeps cats.

No assumptions, only logic can be used to get the right answer and be sure of it. The German has the fish. Don't be tempted to assume, we engineers can't afford to do that. We are the ones who will be held accountable you know.AnkitaDeshpanderight.
the ans is GERMAN
but it comes after assumptions... -
