I wish I had gotten a photo of it when this happened. My first C. versicolor decided that their celebration of a safe shipping and new home was to backstroke in their water dish. I temporarily gave them a large diameter one until I could walk the 10 steps to the fridge and back with a smaller bottle cap, in case they were thirsty. Came inside the room to a T taking a swim in the pool. I thought they had just slipped off the wall or something, but they took another swim a few minutes later that I watched them do.
