Questions on Acro ID and care

[seanb]

Ok, a have a one month old 90 gal reef tank that will eventually have mostly sps. Rock was cured and cycle ended after 2 weeks. All parameters look good and dripping Kalk with a high Alk, stable pH (8.3) and Calcium at 410. So here is my problem, when I ordered clean-up crew online the vendor threw in two free frags! Now I admit I am a newbie, but I was not planning to add sps this early, especially what I am pretty sure are Acropora frags! So I mounted them with superglue and put them high in my tank (actually I had them on the bottom for 4 days and then raised them up). Lighting is 2- 250W HQI w' actinic T5's.
I figure I should try to keep them alive as best as I can.
What if anything should I be feeding them at this point (I have had then for 10 days)? I am having a hair algae problem that is slowly improving, so I don't want to add any more food then necessary.
Here are pics of each one, any chance someone could ID them for me:
Frag1

Frag2

Thanks

Don't feed them anything. You should mount them on small pieces of live rock. They need flow on the base, how they are right now they will start to recede in that area. They look happy they should color up nicely soon after they settle in after shipment. Looks like a formosa and a tenuis?.

#1 looks like a milii,#2 is too small for an id imo.

The pictures were taken before I mounted them. They are now glued to small pieces of live rock. I thought #2 looked like it might be A. tenuis. Anyone else have any thoughts on Frag#1, milli or formosa?
