little green arms

[maui]

I got these four little green w/ black strips in my tank got no idea what they are, but hope they aren't an anemone, lot a bunch of xenia the other week, and water was fine.
Any suggestions to what this could be would be greatly welcomed.

What do they look like? Are they slender? Maybe arms of a seperent star?

 

[maui]

Yeah they're slender and they're on the move.

If they are slender and all seem to be originating from one area, maybe apiece of rock with sevral holes in it, then I would say that it is a serpent star. If it is then congratulations they are great cleaners, but watch out they can grow to be huge. Look in your tank at night, that is when my serpent used to come out of his rock.
