Thanks for posting the info. on the Dragon Tongue.
I've had mine under 36W PC, 80W PC and now 150W MH. It did fine under all three, but has really taken off under the MH.
It always has an orangey color on the front of the leaf, but it is growing like a weed. I don't see how it could be stressed and growing as well as it is. pH? Mine swings from 8.1 at night to 8.3 during the day. Hmmm....
Is yours a solid red/pink or does the front of the leaf have an orange color to it?
I really like your gorgonians! Are there any in particular that do better in nanos?
