well it appears the Daily Mail has caught up with the story, scientists found that fish trained to respond to certain sounds in captivity still reacted months later when they heard them in the wild, researcher Dr Mike Webster said at the time: 'A lot of people have the image of a goldfish with a three-second memory - and that's not the case at all, according to research at Plymouth University, goldfish have a memory span of up to three months - and can even tell the time, the fish were trained to nudge a lever to get food, when the lever was adjusted so it would only work during one hour each day, the goldfish adapted, learning only to press the lever around the right time, also as I have found whilst keeping fish, they can tell the difference between certain colours, but so far no scientists have made note of this fact.
