Probably the most interesting was my Mesobuthus gibbosus and their tail wagging I posted
HERE.
Though my Opithacanthus asper is always pretty funny. It doesn't usually directy go after prey or run from it, it likes hiding with only its chela visible and when the cricket approaches it runs out into the open grabs the cricket crushes it and then runs back to hiding with dinner in hand.
Or one of my Vaejovis puritanus parading around after killings its prey. It kills the cricket, eats half the head and then runs around with the cricket in its mouth.
Now that I think about I probably have at least one story from each feeding.
