Thank you everyone.
I have one adult male YB Spider and he is my best breeder, he has never showed the wobble.
I recently got a female spider baby and she doesn't do it much only when she is over excited.

But then this week, I rescued a spider from someone that could not keep or take care of him and he has it severely, I was very worried about him.
But I got him set up in a clean new environment and got a meal in him and he has shed and just after about 3-4 days he is looking much better and doing less of the wobble.

So is true that it can go away? Could I use him as a breeder?
