Spionid worm | Melev's Reef
This interesting critter is found in most reef tanks near the rockwork or in the substrate of the refugium. The worm (possibly a Chaetopterid or Spionid) secretes a mucous to build a small tube with sand grains (two tubes visible in this image), and extends two 'palps' for feeding.

Harmless but they will continue to multiply on that area of the coral
