The world's most intelligent fish - he plays football, basketball and even limbo dances

Comet the goldfish has been trained by his owner to perform the astonishing range of aquatic activities on demand.

And that's not all - watery genius can also play fetch with a hoop, slalom around a series of poles and push a rugby ball over a set of posts.
Owner Dr Dean Pomerleau, 41, used a training technique called positive reinforcement to train two year old common goldfish Comet to carry out the tricks.
But there's nothing fishy about his claim - in fact, he says anyone can do the same with their own pet.

Fish training expert Dr Pomerleau said: "There is mounting evidence that fish are more intelligent than people give them credit for.
"With the correct tools and the basic promise of a food reward, fish can very quickly learn complex tricks - like the limbo, slalom or playing fetch.

Dr Pomerleau, from Los Angeles, California, has teamed up with pet product firm R2 Solutions to design a special kit to help people train their fish.

The kit features an array of training tools including goal posts, slalom poles and tunnels for your pet to swim through, as well as an instructional DVD.

R2 Solution president Russ Ronat said: "When people see the tricks, after the initial disbelief, they want to learn how its done and teach their own fish too.

"Not only is this product fun, but it also has great educational value."
