What kill my baby blue tang?

[Kevinkmk]

Hi

I have put this baby blue tang in the qt for about 15 days. Copper reach therapeutic level on day 13. Yesterday, I notice it was not eating or swimming at all and just laying down. Today it’s dead with serious hole damage on the fin I have never seen before. Symptoms: head tweaking, mouth wide open ( it stayed open), not moving. Please let me know what it is because I have 5 other fishes already in the qt with 1.875 copper level. Thank you!

What other fish are in the quarantine with him? Was he getting bullied at all? Looks like he may have been getting beaten up a little bit.

There is 2 clown , small Anthias, and a purple tang. However I don’t see any aggression at all.

When I take the fish out today, I noticed there is hole in both of its clamps.

Purple Tangs are mean, if they are not added to the system, either young, or last

The tang's belly looks a bit pinched to me (which could be post-mortem). When did you first notice that it wasn't eating, and had you seen it eat (and not spit out the food) in the past?

That hole in its side could be due to aggression, a bacterial infection, or the other fish picking on it after it passed.

It stop swimming and eating yesterday then it die today. It was fine for like 2 weeks

I don't see anything here that's obviously contagious, so if you "hold course and speed" with your treatment, your other fish should come out OK.

Sorry for the loss of this little guy, though.

I agree that looks like bullying and much of that is probably post-mortem.

Sorry for your loss

What size is the quarantine tank? I'd guess aggression as well from the purple tang. Maybe the blue tang also wasn't eating. But I wouldn't add a purple tang unless I didn't plan on adding any more fish. I also wouldn't put a purple tang in a QT with another tang.

Thanks for all the reply. I hope it was just the aggression. Since it was eating and swimming fine for 2 weeks. However, it was bumping its head to the pvc for like 2 days before it die. The qt is on full copper already. I hope it’s not uronema.
