Hair like parasite coming off my Sailfin tang tail

[Integraonly]

We bought a sailfish tank from our LFS we got it home but it in Corentine and we notice A hair like parasite I believe close to the spot where her stinger is and looks to be another under her tail or the same one wrapped around. At first I thought it was a hair her but it has not falling off yet. It's been 5 days. It does not look like a anchor worm. Can anyone help me please.

Has the tang been through prazipro or any other dewormer?

 

[Integraonly]

Yes 2 dose of PraziPro no difference

Im trying to more or less figure out what it is, so I can then treat for it. I’ve searched online and nothing looks quite like this exactly which makes it hard to be confident about any specific treatment.

Still has the worm like things on her tail.

Did you try a FW dip or a formaldehyde dip?
