Sorry Folks, I was up at my warehouse all day yesterday.
Okay Acrosteve,
I believe that beautiful stag is a A. loisetteae (Super thin elongated branches with tiny radial corallites).
The Monti that you posted is a M. hirsuta. I have one that has finally gotten some color after about 6 months (blue tips with bluish grey branches).
Maggie,
#1 is A. tumida, with busy branches and radial corallites that align along the branch and no secondary radial corallites.
#2 A. sarmentosa, flattened axial corallite, thicker branches and flowering polyps.
#3 Wow what a tough one, I am thinking A. copiosa as it seems the same sort of shaped corallites. But ask me again in a week it I might come up with something different

. This one is tough!
#4 The same as Acrosteve = M. hirsuta.
#5 is the same as #2 A. sarmentosa (at least from what I can see).
Wentreefgirl,
It is very hard to tell at this stage. Some frags are very hard to distinguish as their full structure has not developed. If it does not branch out and stays as an encrusting species it might be something strange and rare like a A. palmerae. But I see some little branchlets starting to come out. I would probably give it 6 months and then retake it and I will give it another shot.
Have anymore? Don't fail me now, isn't there anyone else that I can try and help give a relatively eduacated guess?
I will be around putting new corals on my site, so let me know....
