Ever since I bought these ten dwarf blue legged crabs iv noticed them climbing on top of each other and grabbing each others shells with they're legs what are they doing???
 
Best to get some empty shells, or get more crabs than you want to account for all the homicides.
 
But the thing is I saw my smallest crab on top of one of the biggest ones I have and they just sit on top of eachother
