He is a dancer!! mine dont do that with their legs back and forth, thats cute
they will only get cooler, one of mine just went to L4 i think...lol. lost most of his black...so is now mostley brownish white with black spots, but his spikes got much bigger and his eyes got a purple tent to them.
They are very very cool...and the ball at the bottom of the antennae I think looks very cool and unique
