i've been periodically cropping a green jade sinularia intank without risking it poisoning other tankmates. only material you'll need is a stout fishing line. form a hangman loop at one end of line and snuggle it close to where you want to frag the sinularia, tighten the loop just enough so that the line will sink into coral without cutting it. every two days tighten the knot littlebit more and continue to do so until you have completely sever the coral. cutting this way result in healthy mother and frag with minimal poison released.
