So on the stylos, stylocoeniella (the encrusting one) is a sensitive coral and really needs stability and since your reef is fairly new, I would recommend staying with corals that are a little more forgiving. On stylophora (branches), I honestly find it quite boring and if I was setting up a small reef with limited space, I wouldnt choose this coral. The ones I see are fairly chunky and really dont glow much under the blue lights. They just look kind of black. I think if your looking for a branching coral perhaps a nice neon birdsnest? (I dont have any) or even a pocillopora ( I have some)? BTW -these 3 corals are all in the same family.
Cheers! Mark
