I actually love Seriatopora (birds nest) corals. I have a pink hystrix that was really sad looking when I got it. Now its glowing pink and growing. These guys actually like my ultra bright tank. Flow is important too.
I'm going to snap a pic tomorrow when the 10K lights are on. Now that I think about it, Seriatopora seem to look best under "daylight" rather than actinics.
There are only 2 species of Seriatopora that I'm aware of in the reef trade (hystrix and calendularia) I think that's the second one, someone correct me if that's not it. Anyway, there must be other species. Why don't we see them for sale? Wonder what they look like? Or maybe there's only 2 species on the Earth.
I'll try to put the photo up tomorrow. Maybe someone else has a really nice birdsnest to show?
