Fish show evidence of social intelligence, according to biologist, Culum Brown, from Edinburgh University, Scotland. He has co-authored a report on fish intelligence, and argues that fish can co-operate to find food or avoid predators, punish and manipulate other fish, and seek reconciliation. Fish are able to identify others from the same shoal, and can navigate mazes, as well as use tools and build nests. They also have long-term memories. One fish remembered where a hole was in a fishing net, akmost a year after the fish had first found the hole, Brown records. He argues that captive fish need changes in their environment, to make their lives more interesting.
