The parasite started on the kole tang and now has moved to the regal tang tail. What is it? flatworm/ copepods/ isopods/ fluke/ nematode/ helminth(worm) ??? It will not go away by itself. How can I get rid of it? The kole has had it 13 months and the regal 3 weeks. No scratching or rubing. Both have a healthy appetite. Cleaner shrimp have been short lived because of serpent/ brittle stars (harleguin, bubble tip, red serpent) during molting?
