Okay, i just bought some more liverock and noticed this yellow spot on the side of the rock. its about the diameter of a nickel. Is this a plyop? I am new to this so i could be totally wrong.:confused:

looks like a sponge. Harmless filter feeder.

just a good ol' sponge. Don't worry bout him, just leave him be and enjoy as he grows and pops out some new buddies. Technically he'll help clean your water up by just a smidgen, so be even happier for that :D
