Randy, Mike and Doug,

I have had a pair for a little more than a year, and I have never seen them move their "horns" independently. It is pliable, especially when young and it will stay bent back for a while if they press their faces against the tub walls. It eventually goes back to normal in my experience. Rob Stone, who I got mine from, has never said anything about them being able to move their horns, and I never even thought to ask to tell the truth.

My male a year ago...
