kar93,
I found the article you mention even though the link doesn't work. After a couple PMs back and forth with Dr. Mac, I will be getting some Flatworm Exit the next time I go up there.
darkclamz,
If I had a 75g tank, I wouldn't have issue with a mandarin in the tank but because my tank is only a 30, I feel that there wouldn't be enough food for it and it would starve to death. Sorry, not an option for me at this time.
gary faulkner,
I have and its planned for a future tank.
somewherre,
Thanks for the links. I have done a little research and the best method that I have found is Flatworm Exit which is has numerous cases of success posted. Next weekend I will get some and see how it works out.
