Unknown catfish, weird parasite

[Slayer_will]

When I first got into the hobby probably about 9 months ago I bought a catfish from one of my local shops but they didn't know what it was and neither did I. He's very active and interactive and doubled in size but hasn't grown much in a few months, not really worried about the growing thing but today I noticed it looks like he has some sort of white worm like parasite on his belly near his anal fin, I tried taking pictures of it where you can see it but of course I couldn't get any good ones but I'll post what I have anyway. He's in my 20 gallon community tank, I introduced two small pacu's into it 2 weeks ago and one came down with lymphocystis yesterday and has been in quarantine since than, just want to see what everyone thinks if this could be that also or what? And also if anyone knows what type of specious that'd always be good to know as well, will post any pictures I have of him to get a positive idea on a specious and will also post what I have trying to show the odd looking parasite thing on him

This first one was the best picture I could get of what I think is a parasite it's the one white worm looking thing between his too back pectorals near his anal fin, the rest are just to help you guys to figure out what specious he is

It's a hoplo cat don't know to much about them I know they don't get to big but don't quote me on that.... Imo a 20 gallon is to small a 40-55 gallon would be better for it, definitely get rid of the pacus they are a monsters and grow fast

Hoplo catfish for sure. Can’t see in the pic what ur calling a parasite. If you can bet the fish and take pics up close.

Because it looks like the worm has a fork in it, it could be an anchor worm. Does it look like the long worm like things on this goldfish? If it does, you need to get dimilin-x, Hikari Cyropro, or Microb-lift Anchor worm treatment.

Already have some large ones in my predator tank (300 gallons) and once they outgrow that I have a pond to put them in just have them in their so they can get a little bigger before going in the predator tank. Havnt noticed white poop but will check tonight.

Didn't really look like it had a fork in it more just like a straight line and a lot thicker, same length as those tho.
