I've Solved the Einstein Riddle

Guyz, actually it's my first English post. I'm sorry for my grammar mistakes in this post, cz I wrote it is just wanna improve my English skill. Oh sure, you could gimme some correction. And it makes me happy if you wanna do that. :)

When I was in 3rd grade of senior high school, Rio (one of my close friends) gave me a riddle. You know? It's not just an ordinary riddle. I think it's a greatest riddle I've ever known. Of course, because the author of this riddle is Einstein. Well, I didn't really certain that Einstein have created this riddle. But that's not important for me, I think this riddle is just AWESOME!

Einstein wrote this riddle early during the 19th century. He said 98% of the world could not solve it. So, it means that if you could solve this riddle, you are the part of 2% genius people in the world. Wow! It just makes me more and more curious. :)

Here the riddle:
There are 5 houses in 5 different colors. In each houses lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage.

The question is: who owns the fish?

Hints:

1. The Brit lives in the red house
