They're not going to stick with glue, atleast in my experience. I suggest getting a shallow plastic container fill it with bits of pea sized rubble, cover that with a stocking or veil material , hold it with a rubberband. Toss it in the tank wait a week and wait until they attach.
Or glue and cross your fingers, 9 times out of 10 the polyps fly off into the abyss
