OK ID needed I found something new in my tank

I know I have limpets in my tank. I have many of them. Here is a picture of the ones I have seen for some time.

Well I went to move my glass cleaner and found this

The middle looks like a limpet, but is has a yellowish cover over it. Does anyone know what this is?

Key hole Limpet.

Could it be a flatworm? http://www.polarlife.ca/organisms/inverts/marine_inverts/images/marine_flatworm.jpg

I would agree with the Keyhole/Fleshy Limpet ID (LionfishLair.com - Hitchhiker Guide to your Aquarium)
