Can anyone help me identify this critter. We just discovered their presence in my 29 gal FOLR tank. The one pictured is about 0.5 to 0.75 in long. We observed about 4 additional worms after dark. The largest on we saw was about 1.5 inches long. Is this something to worry about (Bobbit Worm) or are these beneficial to the aquarium. I noticed their presence right after we observed that a clown fish was missing (this is probably unrelated)
Thanks in advance.
