Manual removal is usually best, you don't *need* to keep a six-line or any other wrasse to have healthy clams. Here, we keep a Halichoeres melanurus (Wardley's wrasse) in each clam tank to help with parasite control. However, we deal with alot more clams than most hobbyists. Unfortunately, we recently lost one of the wrasses, he had his head taken off by a 9" T. maxima. We found the body and head sitting next to the clam one morning.. a truly sad event considering the wrasse was at least 5 years old in our systems and who knows how old overall.
