How to move sea lettuce to fuge

[Court_Appointed_Hypeman]

I have a lot of sea lettuce in the display, but nothing eats much of it in my tank. I like the PH boost it's giving me and want to move it into the duge, but my fuge has a decent amount if floe and I don't think it will do well without being attached to something.

How to I attach sea lettuce I pull from rock in my display?

I dont know if it re roots, but loose rubber band would hold it in place
