    Hi there, hope someone can help me. I found something growing on one of my live rock. It looks like a mini clam, about 1.5 cm wide and of a bright green colour (it is still closed). Unfortunately I tried to take a photo but cannot zoom close enough. May be some one with an idea what it could be and also if it is good or bad! :angry:

    Small clams are common on liverock.Most only open a sliver as they are rarely the expensive display clams.
    If it is a clam they are filter feeders and never a bad thing.
