I had corals grow into the glass sides and onto the overflow box. However, they are NOT permanently attached. All you have to do is give it a slight tug and they become undone from the glass/overflow...The surfaces are not porous enough to get a strong hold. If you glue a cap onto the overflow...once it grows out and there is nothing underneath it to support it, it WILL fall down....
