White worm like creature attached to neon tetra

Just noticed this yesterday, and have been trying to research what exactly it is. I have seen him separated from the school hanging out in back of tank amongst the plants, however still seems rather active and eating! Also, I have not noticed any scratching.

The worm is attached at both ends, slightly embedded in the fish's head around the mouth area. Everything I have read online leads me to believe that this is a leech, but I want to get some second opinions so I know how to treat it. I have Coppersafe on hand, however am hesitant to start using it until I positvely identify the problem.

parameters:
5 gallon moderately planted
6 neon tetras.....no inverts
ammonia= 0
nitrite= 0
nitrate= 10
ph= 6.8-7.0
kh= 4 dkh

Here is a pic: (I could not get a good shot of the fish, so I took one from online and drew the worm on in photoshop. It looks pretty close to what I am seeing)


Any help would be greatly appreciated!!!

Well I added a little salt with hopes that it might loosen up its grip but no improvements, so yanking it might be the only option aside from medicating the tank. Not sure if I can do an isolated salt bath for the little guy. I have successfully with other species, but do not know if a neon can handle it. The Thing with pulling it out, is that the parasite is attached right near the fishes eye, plus its obviously a small fish. I guess I will make that decision when I get home from work.

Well, I went in to pull the little worm off and had realized that it was gone. He must of worked it off on his own! There was a little bump on the neons head where the worm had been, but he was happily back with the others. I did a good gravel vac and added some Epsom salt solution I have mixed up. All is well!!
