Fish-lovers have been urged not to feed their pets crisps after bosses at a London aquarium had to wean a giant fish off a diet of Skips.
Gerty, a 16-inch-long, 9lb Gourami is usually grey in colour, but turned an unusual pink thanks to her unhealthy diet.
Staff at the Sea Life London Aquarium are now feeding her a healthier menu of grapes and bananas.
Jamie Oliver, curator at the acquarium, said: "I have never heard of a fish being fed crisps."
He added: "Gouramis usually eat a diet of fruit and vegetation but fortunately Gerty doesn't appear to have suffered any ill effects from her unhealthy addiction. However, we would not recommend feeding fish crisps of any kind."
