Ok, maybe not exciting to most....but we just witnessed our crabs switching shells. One moved out, and into a bigger (bought shell), another, moved out of his shell, and moved into the other crabs shell. Excited....heck yeah! Been waiting for this moment, figured they were just happy with their shells....The one that moved to the bigger shell....he will be set for sometime.....plenty of room for him in his new home....ok, Super happy Hermie Grandma, and super excited kids!!
