What Happens When Coral Stops Growing?

[Marco S]

I have some GSP and a bunch of different Acans, (or whatever they are called now) and was planning on isolating them on there own rocks. My question is, what happens when the coral completely covers the rock and cannot grow anymore? Is it happy staying that size forever or will it eventually start dying?

generally with GSP (not sure about acans) it will start growing over the sand, you remove the bit growing over sand, your loop repeats if you want you can frag the extra

GSP will grow on anything and will even crawl up glass. The problem is with some corals is they compete with each other for space.

GSP can also fragment and blow around the tank to colonize other parts of the tank. Acans will encrust and then begin growing as a dome if there is nothing left to encrust. This will slow them down a bit, but they are still alive.
