Does it move? If so, it looks like some kind of nudibranch to me.

If it doesn't move, does it retract when touched? Maybe an anemone.

Yes it was some kind of slug. I took it out but like I said it was a sulg that had all those tentacles on its back, the reason I took it out was it just stayed on that toadstool and it was starting to turn brown in spots and I just got rid of Tritoniopsis elegans that where eating my coral so I didnt want to take any chances.
