One of the local stores had a few Acros growing for over 6 months under medium level T5s, so I snapped up two types (two on top of LR, one in the left corner):



I'm no expert when it comes to Acro species, but the bright blue/purple one to the rear has large, bushy white polyps and has coralites that look similar to this A. hoeksemai, but not arranged as neatly:



I have no idea about the other mauve colored one with the more slender coralites and no visible polyps (at least not yet). Any of you SPS fans care to hazard a guess?
