Please help, roundworm/fluke?

[HollyFish]

So I lost a firefish to what I’m assuming was roundworm or fluke. I’ll post a pic of it hanging from my firefish’s Gill. I tried to QT and freshwater dip but was too late. Now I’m not sure what to do. I’m buying everything for a legit 10 g QT tank but obviously it won’t be cycled. I have 2 clowns, a chromis, and a spotted mandarin goby in the DT and all seem healthy and fine. Im assuming I need to QT and treat the rest of my fish and my inverts will be fine in the DT. How long should I QT, how often are water changes when not using a cycled QT? Do I need to add copepods to the QT for the goby or just feed frozen? Sorry for the long post, been a crappy last 24 hours for my tank and I don’t want to lose my other guys. Thanks in advance for the help! (Pic of firefish Gill with worm in it in comments)

Tough to see in the photo, but run a Google image search for serpentisaccus that is a copepod parasite of fire fish. If that was it, it won’t affect your other fish.

I literally was about to QT my clowns, chromis, and goby but think you might’ve saved me from doing it. That looks like them. Does this pic help? I would love to not have to QT my fish and possibly stress and kill them if I don’t need to

That does look like the egg case from that copepod....that said, I can’t say for sure that something else didn’t kill the fire fish

After researching it, it looks like you nailed it on the head. I went ahead and set up the QT just in case I need it in the future. Thank you so much for saying it’s name, I’ve posted all over and no one has mentioned this parasite
