Can you identify this Parasite?

I have this Powder Brown Tang, about 100mm long (4 inch). He has been in the tank for 3 months, went through TTM, 2 rounds of Prazi, 3 weeks of observation as did every fish without fail before being introduced to the tank.

Nothing new (Coral, Invertebrates, fish) has been introduced for 3 months. 1 week ago he displayed like this. It looks like worms hanging out of him about 5-8mm or 1/4 inch long. Pretty much looks like a Porcupine with the area where these worms are attached raised.

I initially dosed Prazi Pro and they disappeared, about to redose 9 days later and they returned. I dosed again and made a little bit of difference to the number of them so dosed 3 days later and this is what he looks like. Prazi seems to halt them but not kill them.

Any suggestions as to what they are and how to kill them? I have researched for what they might be and the best I can do is Hook worms.

None of the other 2 Tangs, 2 Angels, 6 Anthias have this condition.

Could be copepods. Dimilin is the answer.
Prazi doesn't work for many worms. Another option would be febendazole. Id probably do both. Dimilin is very safe. Febendazole has potential liver toxicity. Most fish do fine, a few won't. No way to predict.

I researched Dimilin, cant get it in Australia so I got Cyromazine instead, supposed to do the same? All the good drugs are not allowed in Australia without a script and its almost impossible to get one, makes it hard. Thanks for the info, will see if I can get Dimilin in another form. They use it in a sheep dip here so maybe.
