Hey Mike,
They are just the red planaria fws. I really just want to get the nudi, because most wrasses seem to be hit or miss. I have just a few peaceful fish in my tank, and I want to keep my fish numbers low. There are some more fish I want to add in the next few months, so I don't want to add anything else that I haven't planned on. Also, if I do ever actually get rid of all the flatworms, I can get the nudi out easily and trade to someone else on the board that has the same problem.
