Sliced Aptaisia's?

I have recently won a battle with a terrible purple cyanoslime and I believe
my hair algae is beaten almost to the breaking point (thanks in part to this
site for both of those little triumphs). But now, I'm back to my original
problem of the wonderfully resilient aptaisia. I have tried everything but
the Copperband Butterfly (which everyone has assured me will clean em right
out, but only after it eats all my pretty little fanworms...sniff) and the
aptaisia eating slug (the name escapes me, but I don't want to kill them
once they've finished the job, and I'm not growing aptaisia's to feed them
either!). nothing seems to work... I remove the ones I can from the glass
and sand, but you can't get them off the rocks! I have a peppermint shrimp
in one of my tanks that is doing a decent (but slow) job of getting them
under control, but I can't seem to keep the little pep's alive in my other
tank, perhaps due to a condy anemone or my rather big 'eel goby', so I don't
see how I can solve this problem with pep shrimp alone.
However, the other day, I was cleaning the glass with a razor, and I
figured what the %&*#, why not? I cut one of the little buggers right in
half, quickly disposing of the cut off piece. What was left on the rock was
letting go all these little fine white hairs, and shrivelling up. After
about two days it looked like it was going to recover (it was only a little
grey coloured blob, but it started to turn into an aptaisia coloured blob
again) and then, bang, it was gone. This could have been the result of the
peppermint shrimp taking advantage for an easy meal, but if there is a
chance that it just died on it's own, then I may try it again.
Has Anyone done this? I have read that they can spawn when they are
severely damaged like this (i.e. crushed into rock or tweezered) but I'm not
sure that it had time with the method I used. Where the little white
strings some kind of spore type things that are gonna grow into a million
more? Any help would be greatly appreciated!
