Chromis with white patches on fins/body

[Daasmo]

I have 3 small chromis and a melanarus wrasse in an observation tank. They were purchased from LFS 4 days ago from a fresh shipment. Everyone had been eating well but today I noticed white patches and a little faster breathing on the largest chromis. I have not treated with any medications since I got them. Any suggestions welcome.

Looks to be bite marks opposed to disease. Video fuzzy but fish seem active,
Are they eating normal?
Keep an eye on them for any aggression and widening path which would be uronema which is ruled out at this time

Yes they're good eaters.

Yes they've been very active eaters.

They're currently in a 10g should I move them into a 20g? I have copper power and metro but I haven't dosed anything yet.

I watched a bit more. Middle size chromis seems to be the aggressor. Options are to move him to 29g invert only tank or move everyone into a 20g. I'm not ready to put them into my DT yet. Still nervous about it since they weren't fully QTd.

Can you use a tank divider? Moving non-quarantined fish around is always risky.

Are you monitoring the ammonia in the 10 gallon?

I forgot I had an isolation box. It barely fits in the 10 length wise but the aggressor is in time out.

I have a seachem badge and treated the water with prime and used a seeded filter pad for ammonia control.
