this tail nibbling-attack injury, occurs, when a male dominates a cave and another one wants this cave and the male which always has his head first in the cave, does not want to give up his cave. So the weak point of any L is their tail which gets nibbled on or attacked by the other male in order to try and get him out. Most profiles o the L201 indicate that they are prone more to this than others Ls, but it can and doea occur with others as well. cheers jk :thumbup:
