Has anyone had a sea cucumber crash their tank?

[Megalodon]

I have one of those filter-feeding pink knobby cucumbers. It's a year or two old now and it's ever-so-slowly withering away. It's body has shrunk a little and it's feeder appendages have shrunk a lot. I notice J&Ls doesn't carry them anymore. I think I'm going to flush it.

Anyone want it? In light of this thread, which has got me worried, the darned thing is for free.
