The clownfish has rapid breathing

[WEINIXIONG777]

As exemplified in the video
The clownfish breathes very quickly
The opening and closing range of fish gills is very large
Large fish also have white patches on their bodies
What disease is most likely to be contracted in this situation

Because these few fish are all from the same batch entering the fish tank
So it's very likely that they were infected with the same disease

The big fish quickly died after soaking in methylene blue and did not survive

The fish seller taught me how to use TDC（Formalin solution）
I'm not sure if TDC is valid，So I dare not use it

Methelyne blue no good in marine setting and fish in a net hard to determine anything
Please post pics of fish in the water under bright white lights

Welcome to Reef2Reef!

Sorry to hear about the naso tang dying.

The clownfish looks like it might have a damaged mouth, but I could not see clearly.

Does the tank have good aeration? Either an air stone or a good protein skimmer?

Are there other fish in the aquarium that have no symptoms?

It has been confirmed that the fish was infected with Brooklynella hostilis
Because a healthy clownfish has white mucus wrapped around its body

Can you post a video or pics under white light brightness to confirm?

Thank you for your professional concern
The color temperature of the lights is all 4000K
So it looks very yellow
Based on experience, it can be determined that the infection was caused by

Brooklynella hostilis​
