No, I did not loose any fish or coral. I treated 2 times with the flatworm eXit product. The first treatment killed 90% of them, I did not see any results from the 2nd treatment.
I bought a 6-line wrasse about 2 weeks later, and the dozen or so that were still on some corals are now gone, I don't know if the wrasse ate them, if they eventually died, or if they are still around I Just can't see them... But I would say the outbreak is atleast under controll if nothing else..
I think the best thing treat with flatworm eXit, and try to suck them out while they are dieing off, within a minute after treating my tank the first time, the flat works were running off my coral and dieing very quickly. I did run a bag of GAC
after the first treatment, followed by a 20% PWC
