How long can an anemone stay in acclimation box?

[Krixic]

I am getting a black widow shipped to next week, and I am currently thinking about setting up a larger tank. I want to first introduce it by an acclimation box. Im still flipping back and forth on whether or not to upgrade but regardless, how long could the nem stay in the box without irritating it? Until I decide for certain whether I will upgrade, I don't want to introduce it and have it attach to the rock and then have to agitate it to move it to another setup.

Thanks lol. What's a good spot? Direct lighting or should it be more off to the corner?

My csb likes the waters surface at the glass edge in higher par.
Or rather, it has been forced to like these conditions

An anemone can remain in the box indefinitely, no problem. I would do medium flow and close to the surface but not directly underneath your light. Nems are very good at making their environment wants clear and it will walk to the location that best suits it’s needs
