Questions about lps coral growth

I have a prism favia about two months ago that i got with one head on it, when i fed it last night i noticed it had three mouths on the sides of it are those going to grow into corals if so how long usually, and i have a question about my duncan i just noticed like 5 bubbles below the head of the coral does that mean its going to be branching off soon.

 

Pics Please!

But yes, typically when there are mouths or "bubbles" on the coral, they start to become new polyps

I actually have a dragon soul favia that just started growing like crazy- when I got it, it only had 1 mouth and the other was partially cut

 

Hard to say how long, but its already started so keep your water stable.

As for the duncan,, without a pic its hard to say.

 

Ok ill try to get a good picture tomorrow cant tonight dont have my laptop and my ipad wont upload on to this site
