"Wiggler" back - What could be?

Omard,

That sounds like a spaghetti worm to me. http://www.susanscott.net/OceanWatch1998/jan19-98.html

Good link - may be very well what this "creature" is - if, so, it is a "granddaddy" - have "numerous" small spegetii worms throughout LR - very small things, usually seen reaching about in dark.

This thing has "big" arms (tenticles) & has what appears to be a substantial "burrow" in sand under rock. (at least area it has cleaned sand out of)

Expect it is something that was living in rock face that was once on surface, but now down in sand after going in tank.

Will keep eye on - have not had a good view of yet.
