Spionid worm harmless.I have some new frags under observation and one of them is a well encrusted efflo. I noticed some little v-shaped attena looking things coming out of three of the corallites. At first, I suspected vermetid snails, but I don't think that's what they are. No mucus net and seem a little more barnacle type.
Not sure what they are, and I'm trying to decide whether to excise them or leave them alone. Identification will help me decide the best course of action. I appreciate your help
