The end of a beautiful friendship

The owner, identified only as Jameson, was apprehensive when his girlfriend brought home a koi carp for their aquarium.

He suspected that his frog – called Michigan J. Frog – might see the fish as a mid-morning snack.

But the couple were reassured by a pet shop that the two animals would mix well together in the same tank.

Within seconds of introducing the koi to the tank, however, the violent nature of Michigan J. Frog became shockingly clear.

‘No sooner did I have a chance to blink did I see a rapid movement from the frog,’ said owner Jameson.

‘I looked down and saw the majority of the koi’s head in his mouth.

‘His effortless attack on the fish was insane. Most of the fish was still hanging out of his mouth so I started knocking on the tank with my knuckles really hard hoping since he was right at the front he would freak out and let my fish go before he was an official goner.’

The African clawed frog, which can grow up to five inches long, is known as a voracious predator.

It has three claws on each hind foot, which it uses to tear apart its food if it's too large to simply swallow. 

It can be found in the wild throughout much of Sub-Saharan Africa, as well as North America, South America and Europe, but has been known to live up to 30 years in captivity.

But its predatory nature can make it a harmful invasive species, and they have been known to devastate native populations of frogs and other creatures by eating their young.

Users on internet forums on the subject of mixing koi and frogs, however, have warned the both species can be a danger to each other, depending on which is bigger.
