well guys I think you all have nailed it on the head here is a litle something I found on the net
Some are truly parasites feeding on corals, while others more of less scavenge feeding on detritus, diatoms, and dead organisms. Non-parasitic flatworms are of no danger, and most die off due to lack of food source in the Aquaria. One of the aspects that makes some of these worms problematic is that they can reproduce both sexually and asexually making to potential for an explosive population in a short time.
This may be a common scene for those of you whom have experienced flatworms. Planaira like this have reportedly infested soft, and hard corals, as well as Discosoma.If left to their own the worms will certianly multiply. From my observations corals in my system acting as host to the ocasional flat worm never seemed to be damaged by the organisms. Documentations does not seem to corelate coral death with an infestation, or at least directly. In this case they may simply be feeding off the surface of the coral
Removal of these worms if preditation has not been successful can be a simple a a quick freshwater bath. Make sure to follow the correct procedure in the make up of the water and matching the temperature. A 10 second dip should free the worm from the surface of the coral, and then you can return it to it's home in your tank. These worms are so small and many transparent that it would be difficult at best to prevent their introduction to your tank. the picture kind of looks like what I have Im going to try to make them move if I can. Thanks so much guys for your help, you guys are good>>>>>>
