Laetitia, Julian Sprung and I discuss this flatworm and treatments 
for it in The Reef Aquarium, volume 3, however, the Internet forum 
mentioned already is the best place to up to the minute information.

In the TRA3, we discuss the possibility of using wrasses belonging to 
the genus Halichoeres to eradicate the worms. These have proven very 
successful in dealing with red flatworms (Convolutriloba retrogemma) 
infestations, but it is not clear if they would be effective with the 
Acropora flatworms. The two species I have experience with, H. 
melanurus and H. leucurus have been very effective.
