we brought our crabbies home on Sunday. They're still pretty shy, which is expected, but I noticed the smallest one, Pinchetta, seems to have swapped shells twice. It went from a shell that seemed too large (they head to retreat very deep into the shell to fully close it) to one that was the same shape and style that was maybe 2/3 the size. I thought it was pretty cool they found a nicer fit and were making themselves more at home. Today though i see the smaller shell is empty, as is the old shell. Not sure which new shell they chose as all 3 are burrowed under the substrate. Is it common for them to swap so frequently? I was concerned about a possible shell jacking as Sunday we did hear a chirp and the largest crab (Clawington) was very close to the Pinchetta. They weren't acting aggressive so I thought maybe Pinchetta was just in defense mode from the move. Should I be worried? Will they bully one another if the size difference is too great? I have an extra tank and can set Pinchetta up on her own if it'll keep her safe but i don't want to isolate her if it's not necessary.
Any thoughts and feedback are appreciated, as I want to give them the best experience possible.
Thank you!
