Goldfish were once common as every child's first pet.
But now, in the UK at least, goldfish sales have taken a dive, with the number of fish owners falling by half over the past five years, the Daily Telegraph reports.
The number of households with a pet fish is down from 17 per cent in 2012, to just 10 per cent in 2017, Mintel data shows.
The fall coincides with a major rise in people posing with their pets for "pet selfies" to be shared on social media sites like Instagram and Facebook.
But while posing with furry creatures such as cats, dogs and rabbits has become a major craze, fish have failed to make the cut as a selfie-worthy pet of choice.
