NANFA-- Worms. Parasitic?

Here is what these critters do and look like. I have seen this before, but
never paid that much attention, until today.

Some young jewel cichlids I am raising up, one looked kind of thin. I then
noticed the anal opening looked much larger than normal and reddish. I
pulled the fish, thinking it was wounded. The red turned out to be a few
things sticking out. I thought maybe a blockage, maybe shells from
crustaceans. When I pulled them out, they were small clear / red worms.
There were literally dozens in there.

I destroyed the fish. I have seen similar but less destructive symptons in
Fundulus and Lepomis. These seemed to clear up on their own, since I thought
they were blockages.

Are these parasitic worms of some sort? Would panacur treat them? What about
that other one someone mentioned a while back, "Flubeledezone"[sic] or
something similar. There were two with names similar to that . One worked
great, the other not so well with bad side effects.
