i noticed that there are bits of pocillopora sprouting all around my tank. one in my fuge, one on the powerhead cable, others on some rock.
It looks like it reproduced asexually(unless it can self-fertilize) and some of the larvae settled around my tank. This looks similar to what happened with pj86's sun coral. His produced a lot more polyps though.
So far i have spotted roughly 3-4 spots where that coral has begun to grow. Growth started like this - with some stoney circular growth and a polyp in the center
Then polyps started to grow radially out , with one polyp in the center and a ring of polyps on the outer edge of the skeleton.
I find that these new coral growths grow very slowly. They also settled in dim areas of the tank, so that's likely not helping either. but they should be ok - there is some light for them.
I saw someone's 200G+ tank the other day. His pocill also reproduces and starts to grow randomly on the tank sides.
