Re: NFC: Planaria (behavior v. predation)

you can shoot me now for being an idiot---I actually didn't save any when I 
tore down that amphib tank.  Next time I do a water change on the big tank, 
I'll grab out a handful of gravel & see if I can grow any out.  If it 
doesn't work, this summer I'll try with some more mud from the same spot I 
used to landscape the original amphib tank.
