Anemone stuck in acclimation box while trying to get out

[bossjx]

Recently I had an anemone that was moving around a lot and ended up stinging a coral so I moved it into an acclimation box as I planned on selling it but when i woke up I found it trying to get out but is now stuck. Im worried if I leave itll somehow get out and flow onto one of my corals or worse into the powerhead. Does anyone know how to get it back in the box?

Try directing some stronger flow at it, it might make it retract and pull back into the box
