Einstein is an uncannily clever goldfish according to his caring owner Leighton Naylor – an animal lover to the very core.
So when Einstein started experiencing health problems which left him unable to swim, Leighton wasn’t going to stand by and watch him sink.
Instead the 32-year-old set about designing a lifebelt for the fantail goldfish to not only keep him floating the right way up but allowing him to continue to learn tricks.
The warehouse worker said: “When Einstein was a little fish I was training him to do tricks and he was my star pupil.
“I’d get him to swim through my fingers to get food and wanted to teach him fish football too – he could do all sorts.
“But he got this swim bladder problem. They have air pockets in their back to help buoyancy in the water but he was floating upside down.
“Then he sank to the bottom, stuck on his side, and couldn’t go any further. He just looked depressed, the poor fish. I was heartbroken.
“I thought I’m going to have to do something about this.”
So Leighton started designing the lifebelt, drawing his ideas and testing materials to make the finished adjustable around Einstein’s body.
Three hours later the contraption was complete.
Now Einstein is happily swimming again with his tankmates, Leighton’s three other fish Pat, Frank and Blondie.
Leighton, of Holly Road, Thornton, said: “They’re one big happy family now. But he’ll have to wear it for the rest of his life.
“People have said I’m crazy but every animal is a valued family member and I do my best to help every one of them.”
