A US woman claims she owns the world's first musical fish, which can play the glockenspiel and handbells.

Goldfish Jor Jor has been trained to play single notes, chords and four part harmonies by simply using her mouth. The two-year-old tugs on a string attached to the instrument in perfect time to the music playing outside her tank. And she always comes in at the same point when she hears Barbara Streisand sing Moon River. Owner Diane Rains, 54, from Hudson, Wisconsin, says Jor Jor is able to time her aquatic interventions perfectly by listening to the tune.

She said: "Jor Jor certainly is a unique musician. She likes to listen closely until a particular moment inspires her to contribute. At precisely the right time, she will play her bells or chimes for a few seconds only, then swim off satisfied. Moon River has an instrumental intro and then Streisand comes in. Nearly every time, Jor Jor listens for several bars, then just before the vocals began, exactly on the beat, she rings her F bell once."

Diane, 54, started training Ryukin goldfish Jor Jor a year and half ago using a technique called positive reinforcement. When Jor Jor performs a certain act she is rewarded and so is trained to do that act more regularly.

So much for the thirty second memory!

Jor Jor was not the first musical fish...
