Alexandria Miller, from Chicago, USA, says her pet goldfish Gerald is a whopping 12 inches and has to be kept apart from other fish after devouring several of his tank mates
A horrified woman says a two-inch long goldfish she won at a carnival has now grown into a huge flesh-eating monster.
Alexandria Miller, 28, brought Gerald the goldfish home in July 2018 when he was just a guppy.
She thought her new pet was a standard size, but says he just kept growing and now measures a whopping 12 inches.
Now Alexandria, from Chicago, USA, says she has to keep him isolated from other fish as he has eaten several of his tank mates.
