Sleeper Goby just passed this crazy parasite, advice needed

[midwestE]

A couple weeks ago I noticed the dreaded white stringy poop from my sleeper banded goby. I setup and quarantine as he was not really eating and wanted to be ready to medicate him if needed. Today he actually ate two New Spectrum AlgaeMax pellet. Low and behold, i THINK he passed this about 10 minutes ago. It's about an inch and was dead. I tried to feed him the mix of brine, mysis and bloodworms, but that was a few days ago and nothing was in his observation box this morning. Possible it got blown in there

Crazy parasite or bloodworm?

White stringy about 2 weeks ago

Today after a "monster dump"

Any ideas as to what it is?

My next steps is to get him eating regularly if possible (it's been a few weeks) on normal non-medicated food. Then switch to medicated as soon as he will eat regularly.

Any suggestions are welcome, will do whatever I can to save the little bugger.

Ok, I'm dumb and was just wishful thinking, it looks just like a bloodworm :( Different color as it was soaked in selcon and vita chem
