Moving Mushroom Critter?

[4theluvofcoral]

So I have a 125 gallon "reef" style tank with a yellow/blue ribbon eel and Caribbean Reef Octopus and some feeder fish for the eel:sheep's heads, mosquito fish and green sail fin mollies but I noticed this organism that looks like a yellow mushroom but it moves. I took a quick pic and short video of it last night and it's in a different place today.
