Meteor Shower Cyphastrea. I put mine under an overhang and it's growing around the rock out into the light. Awesome colours. I also second the chalices. Low light = Awesome colours... kinda the total opposite of everything in my tank.

I agree with every one else.. the following corals are good for lower light or a shaded light area.

- Chalice
- Acans (lords always best because you can cram pack em in there)
- Dendros
- Sun corals (but require a lot of target feeding)
- Duncans
- Candycanes (mine like the overhang area)
- Xenia likes more moderate low, at least in my tank.
- Toadstool leather more moderate lighting.
- Rics/Yumas are more low-moderate light.

- Feather dusters: not corals, but they add some nice personality and movement to a reef tank.
