ID please - had for over three years now

Hi,

Please see attached. These started out as a pin-prick size and grew to this over the years. I've only got 2x30w NO fluros so I'm pretty hooked on keep 'em alive given it's about the only invert I can keep that grows.

They look like Button Polyps, a Protopalythoa sp.

Any way to make these rapidly propagate? I like them and they seem to like my tank too.

I have on in my tank, but it is a darker color of brown.

More light would probably help, but if you mean how you can get the to spread..you can try butting a piece of rubble up against it for them to slowly spread onto. You can also try chipping the rock away underneath to make more colonies.

But, if you meant how you can get it to grow faster, more light and target feeding with some phytoplankton would help.
