Big Gary, Deputy Curator in Charge of Fish, spotted this article
about fish who suffer from insomnia:
California scientists studying sleep disorders in humans found that some zebrafish, a common aquarium pet, have a mutant gene that disrupts their sleep patterns in a way similar to insomnia in humans.
Zebrafish with the mutant gene slept 30 percent less than fish without the mutation. When they finally drifted off they remained asleep half as long as the normal fish, the researchers at the Stanford University School of Medicine said.
I've heard that watching fish swim around in an aquarium can be very relaxing, but I wonder what effect watching insomniac fish would have.
