mechanical or infection?

[AspiringLobophyllia]

Unfortunately put this wrasse into my main display without QT. From a friend/acquaintance who was taking down his tank. Any idea if this looks infectious or mechanical? It's in a 180g tank, sandbed. I have a fish trap in the system to attempt to get him out to go to QT, just mainly concerned about uronema or related infection with the rest of my display fish. Learned my lesson here. Everything gets QT

In the video, the bird wrasse is showing aggression towards the new wrasse, who has a bite removed from its dorsal. The other injury, probably mechanical but an image under white light would help with identifying the current status of the wounded area.

I'd say it's mechanical damage from netting/transferring.

This is an injury from object and dont see it as aggression injury. I also see fin damage suggesting a squabble involved and likely from rocks in which some appear to be with sharp edges. This should heal on its own but keep an eye on area for healing and not becoming red or sore which would require treatment using seachem Neoplex in a separate tank

Thanks everyone for the input. Definitely helps me feel better, I will keep a diligent eye and set up a QT tank just in case things get worse

It seems to be injury - I personally can't tell without a white light picture. In the future, would take pictures under white light which makes it much easier.
