Fifteen or sixteen went in; most days we can see ten.

But they seem to be happy enough, the kids in the neighborhood love having fish in the creek (such lucky kids, to have a creek in their childhood) and although we might have provided a few treats for the raccoons (where are those other five or six fish?) it seems to have been a good idea, or at least an entertaining and relatively inexpensive one. I imagine it's got to be better than being in a brightly lit fishtank at Wal-mart, with kids tapping constantly on the glass with their smudgy little fingers.
