Can seahares reverse?

[my2rotties]

Well my seahare is stuck in a tunnel. His head is stick out a narrow hole and his big arse is stuck in the tunnel. He has not moved for a couple of hours and I am thinking he cannot move back. I know he cannot go more forward then he is. I can see the front of his head in the tunnel but nothing else. If he is stuck I have to take apart the entire rock work to get him out.

It kills me to do it, but I will help him out. However I would rather wait and see if he can go backwards, or should I just resign myself to ripping the tank apart.

SO... can they can g backwards and maneuver?
