""It was somewhat controversial to start feeding the fish," says Wilson.

The pupfish also enjoy the extra shelter of some plant material that wildlife managers attached to their rocky ledge, to give them increased shade and more options for hiding — because the older fish aren't above eating the young'uns.

"I think society has a duty to protect species that humankind has negatively impacted," says Wilson. He points out that groundwater pumping lowered the water level in Devils Hole, and the top of the pool is about six or eight inches below the historical pre-pumping level.

The Devils Hole pupfish is famous in conservation circles. It was one of the first species to be listed as endangered under the Endangered Species Act. After nearby development threatened to siphon water away from its lonely refuge, lawsuits aimed at saving it went all the way to the U. S. Supreme Court."
