In pain and ill Snowflake eel...what to do?? :(

Okay,
For the last week he hasn't been wanting to eat and I didn't think anything of it due to that being common every once in a while for snowflake eels, but just last night I caught him doing this and now think
there is something more. I cant honestly think of what could be wrong. I added the video so you guys can see and maybe even possibly help. It almost seems as though he has a crook in his neck and cannot swim
right. What would cause this.
I just did water test and everything is in tip top shape. What else could be wrong. He has never acted like this. I am very persistent about weekly tank cleaning and water changes. I feed him frozen shrimp and krill
(more shrimp has been on his diet lately).
My poor baby seems to be in a pain and I dont even know if there is anything I can do. Any advice is welcomed!

Also, I have read a little and it seems to be with something with his slime coat (noticed the stringing stuff on him?). Anything to fix that? Any vitamins or meds recommend? Thanks.

How is he doing now?

Sorry, been quite busy.

Well what ever it was, he is no longer doing his sad swim. He has actually started eating again. I see some hope for him. It just really bugs me because I have no clue what was wrong with him. Thankfully he is doing much better. Actually surprised to see him come around from that. I was truly scared I would be saying good bye.

Maybe he just had a really bad itch and couldn't quite reach it

Glad to hear he is better

I spoke to soon. Last night after coming home he was doing the same thing. My husband woke up this morning to him passed away. I am quite shocked because I really thought he was doing better (started eating and every thing!) and all of a sudden it turned ugly. RIP snowflake

Oh, darn, I'm so sorry. Too bad we really dont know what happened.
