shaking back legs?

[tylerl19]

when i put my beardie in his feeding 10 gallon tank tonight his back legs shook like a dogs when its itching. like twithing almost. the tank bottom was cold so i am wondering if this is something serious or a random thing. he has done it a few times.

Shaking could be a form of calcium deficiency. are you dusting your feeder with calc powder?

Trembling limbs is a classic sign of MBD. Check to make sure your UV lamp is putting out enough UV and/or give him some natural sunlight (directly, not through glass). For a quick recovery, though, I'd take him to the vet where he'll get some liquid calcium stuff to take daily.
