I have that book. It suggests Surgeonfish, specifically members of the
Zebrosoma genus, as well as angelfish and diadema urchins as well as removal by hand for control methods. Not really much info but it raves on about the desirable filtration effects. It also mentions that
C. lentillifera (grape caulerpa) and
C. nummularia (which I just discovered a patch of, &^$%!) are particularly difficult to control and can smother or injure corals.
