So I got a regal angel fish(yes I know) but had a purple tang in the tank when I put the angel in the tank from observation. The purple tang was being a jerk( aka a tang) so I caught him and put him in the observation tank. How long should I leave him in there 4 days ? 2 weeks? Im taking down observation tank after so don’t really want re set it up after. I knew I may need to do this so I was prepared
