Sniperhank said:Nice duncan! I had one like it and loved it. You don't actually need to feed it at all, just make sure it is getting enough light. I'd say it is since it looks so happy. Maybe once a week if you want to feed it something small. I used to feed mine once and awhile just because it was cool to watch.
Readingexcalibur said:Awkwardly, I found that the Duncan will grow larger if you don't feed. I believe this is because of its branching style of growth. If you feed shrimp, etc, it will stay content. But if you let it filter from the tank, it will grow more heads to support the colony. Just my 2 cents.
15 heads in 6 months on my ORA purple Duncan.
Sniperhank said:There are several different morphs. I had one that was entirely purple and currently have 2, one is entirely green and the other has a purple base and appears to have green heads. To my knowledge they are all the same thing, similar to different zoa morphs. The only place I have seen a duncan listed under anything differently was on saltwaterfish.com having a duncan and a duncanopsammia under their SPS section, even though it is even labeled an SPS. But the scientific name is Duncanopsammia axifuga for all I've seen.
