I recently upgraded to metal halide lighting and am wanting to start dabbling in SPS. I acquired a birdsnest frag last week and it is doing really well- polyps are fully extended, good color, and pale on the very tips showing new growth. I am wanting to add a few more frags but don't know which are good beginner SPS. I am interested in Stylophora, but different sites show conflicting information on the level of care. Also interested in montipora digita. Can someone please point me in the right direction to some good ones to start off with?
