Pics very fuzzy and almost too close. Need clearer pics but may be trematodes or Piscicolidae worm. Need to confirm though

Hopefully better?

Googled both, not really sure. It looks like a reddish tube with 2 curly cues coming out of it and pretty long.

Just went on a larger screen and looks so much like a thread worm but they are mainly freshwater

Found this, closest thing I can find. A reply from @Jay Hemdal on the second page here along with yourself.

Ah yes, egg mass.

Found someone else with the same parasite on a goby:

I think it may be Cardiodectes bellwoodi, which hosts more than just firefish and appears to have a more prominent body on the fish:

Those are copepod egg cases. Don't try to remove them, as the female copepod is deep in the fish and pulling her out will damage the fish. Luckily, most copepods don't reproduce in aquariums, although this infection may prove fatal, it won't spread.

Here is an article on higher parasites of fish:

I can narrow it down to "probably something in the Cardiodectes genus" though @ISpeakForTheSeas may be able to help from here.

Thank you all for your expertise and help with this!

Good morning Jay, I always thought that copepods did reproduce in aquariums? Just curious here.

Call your lfs or whoever you bought it from, tell them what is wrong, ask what you can do, maybe try and bring it back for refund? or you can get medicine for it.

These species typically have a planktonic larval stage that really has a difficult time surviving in home aquariums (they tend to get filtered out before they can mature and infect new fish).

I think I'd have to see the pod removed in this case, as I haven't researched these types of pods yet, and at least a few species from the genus have similar-looking eggs; I would guess postmetamorphic adult female Cardiodectes as well at this point, though.

Unfortunate to find on your fish, but those eggs spirals are pretty cool.
