Tank is only 3 months old and I just found 3-4 of these tucked up in the caves of my live rock.
Only active in the dark.
Multiple long, thin, whipping, prehensile, tentacles that are a little thicker than a horse hair and like 2-3" long. Bodies seem to be tucked into the rocks.
Seem like harmless filter feeders, but also watched one snag a decent sized amphipod.
Sorry best pics and video I can get in the dark on my phone.
Spaghetti Worms possibly? Didn't know they lived in the rocks or got this big.
