What's this?

[Mountainreefer4339]

Does anyone know what the two seeming little antenna are on my snail here? They are whitish in color and quite wispy flowing in the current. They are not the snails antenna as they emerge from the top of the shell. Just got this guy today from the lfs. Thanks in advance for any help you can give...

I see this alot in my tank too, on snails and a few on some montiporas. I'm assuming it's some kind of harmless burrowing worm and all we see are it's antennas/filter feeders. I haven't seen it hurt anything as of yet.

Could be a spionid worm ? They are harmless

Could be a barnacle, they can grow on coral as well.

Thanks everyone for your help. I'm still pretty new to the hobby, so to my untrained eye I was afraid it might be aiptaisa babies.
