I Need I.D. Please...(Strange)

[meehan6587]

O.k. first off I have a 29 gallon tank that i'm turning into a reef. Already cycled and I have about 35 lbs of live rock. So I left my house for a few days and returned and say this "thing" in my live rock cave. At first I thought it might be eggs (I have two percula clowns) but I doubt it. I was wondering what any of you thought click the link below...
Can You I.D. This?!?!
P.S. Tank levels are normal, temp, salinity, 40 lbs LS, 35 lbs LR, Two Percula Clowns.
-Thanks
