Trevor,
I figure that the current was so strong when it went to switch that it was caught by the force of it and was plastered against the rocks. I saw it do this a couple of times trying to get to the shells. Was funny to see. Like a leaf on the breeze.
Beverly,
I just treat all the animals in my tank with the same care that I extend any pet or thing in my care. Now if my Dottyback was still around that hermit would have been toast in 2 seconds.
