Bully fish isolated in mesh breed box

[tinytanya7]

Bully fish has potentially killed one fish and left another with intense tail damage. I isolated them in a small mesh breeder box since I do not have another tank.

How long should they be isolated?

Will the isolation hurt them? I am concerned because they are closer to the light bulbs.

Any tips are appreciated.

Video of the fish being a bully, and picture of them in the isolation box.
