Consider yourself lucky if that dies. If you stick with this hobby you will hate those more than anything on earth.

That's just how ots growing. It mats over your rock. I've seen GSP stay CLOSED for over a week then open back up only to look even better than it did before.

As the above poster stated, yes it can get out of control if you have a thriving tank for it. Some like that some dont. Personally when I have it I leave it on a solitary rock not to touch my rock structure.

I disagree with all that talk that it grows to much I have just been fragging it and making my money back very good coral for making money
