definitely slug of sorts but looks like it may be related to sea hare family they usually eat algae however some can eat corals , sponges etc but not sure about this species check out seaslug forum reference pictures

The Sea Slug Forum - Species List

this is not something I would trust with corals

Could be this one...although it's VERY hard to try and ID them...GENUS: Dendronotus sp...

I would be very nervous about keeping it in my Tank as it's NOT from the FAMILY: Elysiidae

yea also came to the conclusion its in the suborder Dendronotina

when i see him again - will remove him they seem to like the softer polyp corals wich isnt a good thing for my daisies

If it has blue spots on the side REMOVE !

We found they DO EAT CORALS starting with soft but not minding a nibble on a few LPS's as well

and try not kill it, put it in your sump

I would agree with you on that.
Most of these buggers eat softies like Sinularia and Lobophytum.
They can cause quite a bit of damage, be hard to spot and cause polyps to be retracted in area where they are located.
Found a couple similar looking ones a piece on live rock with clove polyps on it.
They now live in my sump.....

Some of them a really very beautiful but not too friendly on corals....
