The new polyp i got was attached to sand i have it in the bottom corner of my tank but i want to attach it to a rock ...how do i do this ...oh i want to move it because he won't open and i do'nt think it's getting enough flow.
'reef' glue is simply slow-curing super glue gel. You can get that at any walmart or hobby store
What they mean by sandwiching the item between rocks is simply tucking it gently in between to rocks so it doesnt float away.
A pic would be handy here. But, it sounds like it's a mushroom. I would simply glue the dand to a piece of rock and call it a day.
