SPS ID Help please

Hi all,
I've had this particular Acro in my tank for over a year. When I got it, the tips were covered with a really tough "turf" looking algae and the entire colony was a dark green in color. It's now algae free and the color is lightening to an almost baby blue color. Any ideas?

tenuis? vermiculata? ID'ing is really not always easy.

looks tortish to me with the long coralites..

Definitely not a tenius. I have several A tenius and it looks and grows nothing like them. A. vermiculata seems to have very evenly spaced and scale like corallites, but it's a possibility. It's also been suggested that it could be A. austera or A. aculeus. I'll probably have to allow it to grow more and get another pic at that time. Thanks all!!
