Nice fish may not finish last, but they may be more likely to get caught, new research shows.
The bluegill, a fish found throughout the U.S. Midwest and South, is not terribly difficult to catch and many consider it quite tasty.

Bluegill are relatively gregarious fish and tend to hang out in groups. The more social individuals play an important role in helping the group find food, locate choice habitat, and avoid predators, says Mike Louison, a behavioral biologist at McKendree University in Lebanon, Illinois, who completed the study as part of his doctoral studies at the University of Illinois.
