I noticed these above one of my cyphastrea frags. They are clumped together and seem to be about a dozen or so. They are green and look like bb-sized and firm but translucent. At first I thought it was bubble algae but these aren't showing up anywhere else in my tank. Are they eggs from a snail? I have about 5 Trochus and 2 Turbos. 4 clownfish, firefish, fire shrimp, cardinals and coral beauty. Sorry for the lousy, blurry pic...
