I found this slug like creature underneath this rock. I found it because I noticeed my colt coral had been deflated for a few days. THe base of the colt is white and looks damaged. Was this slug the cause of my coral's tissue loss? The slug looks very spongy at the perimeter of the animal. It seems to be light sensitive and prefers the underside of the live rock. I saw two distinct antenna. THe body was transparent and I could see the internal orgams. Sorry the pic isn't that good. I'm goign to try to use a different camera tomorrow.

Need a much clearer picture but most likely a Tritoniopsis sp. nudibranch and yes you are probably seeing an egg mass too.

I found another smaller one munching on the base of my colt coral. In an effort to save my colt, I sliced him into 3 pieces and removed both slugs. I'll try to post some more pics later.
