I got this acro a few weeks ago mainly to see if I could keep it alive. Well it has so now I would like to know what I have lol. The base color is green while the extending branches are purple.
It is hard to say by the pictures. Can you get a picture with more white lighting, maybe a flash? Step back a bit and get it in focus.
It is really too small to get a precise answer. So far I only see some tips and can barley make out the corallites. to be a little more sure it will have to grow out some more until it gets a structure growing. For now I would just leave it at Acropora.
