U.S scientists say they have discovered why male guppies, the most fertile member of the fish tank, are so colorful. The University of Illinois researchers, working in Trinidad, say the answer is genetic, with vibrant colors used to attract females. The investigators found the most colorful male guppies exhibiting the rarest patterns are most likely to survive in the wild, as compared with males with more common colors. The scientists say that predators apparently experience difficulty in targeting the fish with rarer patterns. The study's findings appear in the journal science. Cat-Eat-Chocolate
