Meet Big Bob, The Foot-Long Goldfish Who Keeps Outgrowing His Tank!

If you think goldfish are always tiny pets that can be kept in a small tank, think again! Joseph Curtis has an amazing piece on the Mail Online about Big Bob, a foot-long goldfish who keeps outgrowing his tanks!

Three years ago, Anne Cooper, bought two goldfish from a pet shop in Scarborough. Each little fish was only an inch long. But the 56-year-old mother says that Big Bob just won’t stop growing! Big Bob has managed to outgrow four fish tanks in the three years since Anne bought him.

Now he’s a foot long. He’s the same size as a full-size Subway sandwich! He even manages to scare her two cats away by thrashing around in his tank. Being so big has clearly given him a huge appetite, because he demands to be fed twice each day. The scary fish has a bad temper and hates the color red, charging the side of his tank when he sees anything red.

Ms Cooper shares:

“Bob seems to be still growing and I have no idea when he will stop. How big can a goldfish grow?”

“I am going to have to get another new tank now as he is now too big for this one – despite it being about five feet long.”

“He is more than a foot in length and shows no signs of stopping. His size is quite intimidating to the cats who often approach him but if he moves suddenly then they run away in fright.”

“Most people think goldfish are stupid, simple creatures with no personality but Bob is the complete opposite.”

“He seems quite intelligent, he knows when his feeding time is and he knows what food he wants. He also has a bad temper when he doesn’t get what he wants and often gets quite angry!”

“The lid is always on the tank but it doesn’t save me when he has a tantrum – there are gaps around the edge and Bob will thrash around and throw water out with his tail.”

“It usually escapes through the gap and soaks anyone or anything in range so the fish tank has to be kept away from everything else.”

“On one occasion my son Anthony left a packet of Skittles on the side by the tank and Bob went crazy, dashing up and down, splashing water everywhere and even bashing his head into the glass.”

“He does this whenever he sees something red now. He must think it’s a rival – I have a violent goldfish!”

Ms Cooper talks about Big Bob’s diet:

“Bob is already very fat and I try to cut his food down but he gets frustrated if he isn’t fed.”

“He gets through quite a few pond sticks and fish flakes every morning and every evening and gets agitated if I’m late with them.”

“Then every Sunday he joins in my Sunday lunch. I had been told that garden peas were good for him but now he’s been so spoilt he demands them every Sunday.”

“I usually give him a handful but I have to feed him them one at a time, with Bob coming to the surface and grabbing them from my hand. He’s a very lucky fish.”

Ray Rich, the 60-year-old editor of the Goldfish Society of Great Britain’s bulletin says:

“I breed goldfish myself and have never managed to get one this big so congratulations to Anne.”

“Bob’s size is definitely unusual, especially considering he is kept in a tank.”

“Goldfish usually grow with their environment so if they are in a large space and are fed enough, they do sometimes just keep growing.”

“If you went and checked the lakes and ponds across the country you could probably find a goldfish about Bob’s size, but having one in a tank like this is most unusual and I have not heard of one.”

“It is a testament to Anne’s good goldfish keeping that Bob has grown so big.”

She also owns two female cats, named Smudge and Cassie, who both seemed to be frightened with Big Bob:

“The cats are quite intimidated by him. They will watch him warily but if he starts thrashing about they run off and hide.”

“They definitely seemed scared by him – it’s almost like he is the boss of the house.”

“Bob often thrashes around so much that he throws water out of the tank so we have to keep electrical items away from the area.”

“The cats have been soaked by flying water before, which they hate – so this is probably why they are particularly scared of him. Unlike other fish, he can actually get them!”
