QuoteWoman badly bitten by piranhas
If you're leaving your piranhas in the care of your mum, you'd think it would be a good idea to let her know what she was dealing with. However, one mother wasn't quite so lucky and suffered a nasty wound after one of her son's "goldfish" latched on to her hand while she was cleaning out its aquarium. Doctors said she lost all of the skin from two of her fingers and was lucky not to have lost her hand in the incident.
