Toadstool ripping hole in the middle?

[Notsolostfish]

iv had this toadstool for 2 years now. Its growing big from a small frag. But it has a hole in the middle is it because how heavy and big its getting? Attached some photos below. Sorry for the coralline algae need to clean the glass. Thank you
