Acan ID?

[AaronFReef]

I have had what started as a small frag of “acan” almost a year ago turn into a large acan ball on my sandbed. Moved it up to the rock to try and encourage it to put out skeleton on the rock laterally and stop just growing so much tissue in a ball around the cut skeleton below it. It’s heads are up to 2.5” on the topmost heads.

question one: is this how to encourage it to become an encrusting, spreading colony?

question two: what is this called really? I didn’t think acans got this big per polyp and wonder if it’s really another type of coral.

Its a micromusa lordhowensis ,they like flat things like tile or plugs to base out most quickly, if you put them on nubby rocks like that it will take a long time for them to overgrow the nubs
