Okay so you know how at grocery stores and the like, all the lobsters have their claws rubber-banded shut? That's partly for the protection of staff, I imagine, but it's also because lobsters are super aggressive and will literally rip each other to pieces if they're put in high-density confined spaces like that with minimal topography. My exhibit isn't nearly as bad as a seafood counter tank, but it's still a small space with a limited number of hidey holes. So, to keep them from killing each other, we close their claws, but we use glue rather than elastic bands because it's a little less visually obtrusive. Sometimes, though, the glue breaks, so we have to pull them off exhibit, re-glue the claw, tape it shut, and keep them in a holding tank for a few days until the glue cures. Ergo - timeout to keep them from killing each other.

Both of my ImaNaru lobsters broke open their claws last week, because I swear to god these two actually can't do anything without the other one copying. It's bizarre. They even moulted at the same time.
