Key Worm Eel

[Fishheaven123]

Has anyone ever had one of these in their tank? Are they harmful to a reef tank? Any input would be appreciated.

I would imagine, like other eels, it would eat whatever inverts and small fish it could fit in it's mouth. I don't think eels in general bother with coral, but shrimp and small fish may end up a tasty treat.
