Answer:

The German owns the fish.

Solution:
The Norwegian lives in the first house (9) and next to the blue house
(14) so the blue house is #2. The Norwegian's house can't be green or
white (4) or red (1) so it must be yellow, smokes Dunhill (7), and the
person in the blue house keeps horses (11).  Since the person in the
middle house drinks milk (8), and the owner of the green house drinks
coffee (5), the green house must be #4, the white house #5 (4) and the
Brit in the red house (1) drinks milk in house #3 (8).  Since we have
determined the Norwegian smokes Dunhill (7, 11), he doesn't drink beer
(12) milk (8), tea (3) or coffee (5), he drinks water, and the blue
house owner smokes blends (15).  Therefore, he can't be the German (13),
and because we have determined he raises horses, (11) he can't be
Swedish (2).  With the Norwegian at house #1 (9) and the Brit in #3, The
only nationality left that can be in the blue house at #2 is the Dane
who drinks tea (3).  With the water drinker at house #1, the tea drinker
at #2, the milk drinker at house #3, and the coffee drinker in #4, the
beer drinker who smokes Bluemaster must be in house #5, which can't be
the Norwegian, the Dane, the Brit, or the German (13), So he must be
Swedish and keeps dogs (2).  The Brit must then smoke Pall Malls and
raise birds (6), the Norwegian raises cats (10), and the German who
smokes Prince (13) must raise the fish.
