Is this a worm on a shrimp?

Just above its right eye.
I’ve just bought 7 cherry shrimp and into the tank they’ve gone (note to self about quarantine).
Then I saw this thing on this little fellow…

Just seen this thread by Colin:

Neocaridina shrimp worm

Hi guys, So I have just been enjoying looking at my little 35L shrimp tank and I noticed that 1 of the blue dreams has got a worm attached to it's head, I have heard of this before and the common answer would be "Scutariella japonica" but it doesn't look like any of the pictures I've seen...

Have started treating with aquarium salt.

Right, so confusion abounds and I’ve attached the worm-by-the-right-eye photo and a one-hour-later-after-salt photo which seems to show the worm gone?
What is happening?
And can you all nod appreciatively at the effort it took me to find the same shrimp in a tank of 7 red and white shrimp

This time with photos attached…

Sorry you haven't gotten any replies on this matter, but it does appear that the worm is gone...for now, at least

Glad that you found a thread that was helpful

Here is another photo of the “worm” in profile from earlier today. Just below his right eye, curving downwards like a horn. And a photo of his face now. It is definitely not there now.
What could it have been?
And could the salt have worked that quickly?
Do I need to worry about the health of my tank?

Possibly a planaria, which is not good news for the shrimp...see the Youtube video on this page:

One moment, please...

I think I've found what it is/was: Holtodrilus truncates.

I looked at this website: https://aquariumbreeder.com/holtodrilus-truncates-parasites-in-shrimp-keeping-hobby/

Which included this YouTube video:

Which is exactly what it looked like.

Each shrimp has now had a salt bath, and I'm treating the aquarium with salt. Wish I knew where it had gone...
