Axolotl backward/upward legs

Hi all!

This will be my first post asking for help/advice!

I bought this gold abino (Nova) roughly about two weeks ago from a breeder local to myself and I did notice that Nova's back legs looked odd but decided to go ahead with the purchase anyway.

Looking more in depth I have become more concerned with his hind legs going upwards (as you can see in the attached pictures)
In terms of walking, he does manage but I feel that it doesnt look correct - he uses them like a rotating watermill to propel himself forward, but he swims perfectly fine when he goes up for air.

My question is, should I have someone look into this or will it correct itself with their regenerative abilities?

Thanks for the help in advance!

Axies usually lift their legs like that when they need to poop. What are you feeding him?
