Nana, I think this one was previously posted, although quite a while ago and perhaps before the time of most current Denizens.

And since it's one of the better puzzles of its type and well worth the solve, people may want to give it another shot.

For those who do, two things need to be assumed:

[1] that one of the house owners does in fact have fish as a pet.

[2] that "first" in the sense of Clue 9 means "leftmost" in the sense of Clue 4.

With those assumptions the clues give an unambiguous solution.
