The German owns the fish. This is a classic logic puzzle that requires careful deduction.

1. Start with Known Facts:

• Norwegian in 1st House: This is our starting point.
• Norwegian next to Blue House: House 2 must be blue.
• Milk in Middle House: Milk is in House 3.

2. Deduce from “Blends” and “Cats”:

• Blends lives next to the cat owner.
• Blends' neighbor drinks water.

3. Deduce from “Horses” and “Dunhill”:

• Horse owner lives next to Dunhill smoker.
• Dunhill smoker lives in Yellow House.

4. Deduce from “Pall Mall” and “Birds”:

• Pall Mall smoker rears birds.

5. Deduce from “Green House” and “Coffee”:

• Coffee is drunk in the Green House.

6. Deduce from “Ukrainian” and “Tea”:

• Ukrainian drinks tea.

7. Deduce from “Spaniard” and “Dog”:

• Spaniard owns the dog.

8. Deduce from “Englishman” and “Red House”:

• Englishman lives in the Red House.

9. Deduce from “German” and “Prince”:

• German smokes Prince.

10. Deduce from “Bluemaster” and “Beer”:

• Bluemaster smoker drinks beer.

11. Fill in Remaining Details:

• By process of elimination, we can determine the following:
  • The man who smokes Blends lives in House 4.
  • The man who smokes Dunhill lives in House 5.
  • The man who smokes Pall Mall lives in House 1.
  • The man who smokes Bluemaster lives in House 2.
  • The man who smokes Prince (German) lives in House 3.

12. Determine who owns the fish:

• Since the German lives in House 3, and the fish owner lives next to the water drinker (who lives next to the Blends smoker in House 4), the German must own the fish.

Key to Solving:

• Systematic Approach: Start with the most concrete clues and gradually build upon them.
• Charting: Creating a table to organize the information (houses, colors, nationalities, drinks, cigarettes, pets) can be helpful.
• Process of Elimination: Use the given clues to eliminate possibilities for each category.

This puzzle demonstrates the power of deductive reasoning and the importance of a systematic approach to problem-solving.
