i was watching the tank last night after the lights went out and moon came on ....and the arrow crab was just cruising to the top of a piece of ornamental coral and started shedding its skin/shell?? so unbelievably cool, we sat for quite awhile in the dark watching it , so my question is ,,do i remove this skeleton or leave it, is it beneficial for anything , harmful??
