my saratoga was a lonley man so i desided to buy him a tank mate. ends up the mate i got him turned out to be carrying anchor worm and now my toga is infested, i keep pulling them out and treating the tank but they keep comming back on him in different spots. 10+ at a time. only meds i can get in aus say "not safe for saratoga" i have done a search and found that copper sulfate will kill these guys thats my next step any other advice on killing these bastards?
