Geez... hopefully not, since I haven't seen the whole thing come out of the rock yet I can't confirm. I looked at Ronald Shimek's inverts book and he say's polyclad's are hard to keep alive in the aquarium so will likely perish? I have digitate hydroids on the same rock so if I find out it is a polyclad worm I may just get rid of the rock. I was planning on waiting out the hydroids because I read they do not last forever and usually cannot live in an established tank for long.
