London, May 6 : Comet, the goldfish is surely on track to become the smartest fish in the world, for it can perform a range of unbelievable aquatic activities.
Comet can dunk a basketball, score a goal at football and limbo under a bar.
The two-year-old fish can also swim through a tube and collect hoops, slalom around a series of poles and push a rugby ball over a set of posts.
Comet has gained this amazing ability after the positive reinforcement training by owner Dr Dean Pomerleau.
The wonder fish's technique is the same as those used to train dolphins, according to Dr Pomerleau.
This involves rewarding the fish with food when it successfully completes a task.
Dr Pomerleau insisted there was nothing devious about his claim, saying anyone can teach their pet to perform similar tricks.
"There is mounting evidence that fish are more intelligent than people give them credit for," the Telegraph quoted him, as saying.
"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.
"Now people in the market for a dog might want to consider a fish instead," he added.
