Fish are not herd animals that simply react in school to changes in their environment. Research with rainbow fish has shown that they have quite complex personalities.

When the fish were placed in a water tank that was strange to them, they reacted differently to the stress situation: some of the fish tried to hide, others tried to escape, and still others cautiously explored the environment. Moreover, according to the researchers, each fish retained its own personality when placed in a different stress situation.

 
"That may indicate that the traits are tied to specific genes," says researcher Alistair Wilson, who has a taste for the idea. "The idea now is to get a better understanding of evolutionary processes and to see how different behaviors can persist as species evolve," he says.
