Reply to comment by JetAmoeba in Scientists have proved goldfish do have good memories and are able to navigate their surroundings. A team from Oxford University trained nine fish to travel 70cm (2.3ft) and back, receiving a food reward at the end.

I have a colour changing light in my tank that moves between blues and greens, but at 5pm the tank goes red telling me to feed the fish. When the tank goes red the fish get agitated and hang about in the feeding corner.
