3 microcrabs fighting?

[Bsurfr]

2of my small microcrabs are holding a larger one one on top, the other on bottom. Are they breeding, fighting?

Like two crabs pressed together..or..? I'm having a hard time picturing this.

Yeah, one was on the larger crabs back and the other looked like it was fighting to get on its back also as the larger crab was trying to pry it off with its claws. Looks like the two little ones were jockeying for position
