Worm-like critters

[RSF]

I had a fish die over the weekend and now I'm seeing this for the first time, so I am a little concerned. Post hoc ergo proper hoc and all that . Any idea what this is and if it is a concern?

I dont know much about flukes but from what I do know these might be them.
You should post this in the fish disease forum to see what the specialists think.

If your fish had flukes and died they may be looking for a new host.

Thanks, I posted it in the other forum.

I think they look like a nematode, but if those are on the fish you can see them.
