[whyamisofl]

I tried searching for this.....I can't be the only person that doesn't know!!

I know I have acan and favia in my tank........but have no idea which is which.
#1

#2

#3

And then #4, I assume it is some sort of digitata?

More of #4

no 1 favia
no 2 acan
no 3 acan *?* cant tell pics too blurry
no 4 is a pavona (I believe)
