Mummy Eye Chalice Losing Color

[Magician8642]

Hey Everyone,
Hoping for some advice on care for my mummy eye chalice. When i first purchased, it was bright green with about 10 bright pink eyes. It was about the size of a half dollar. My tank is a 120g + refuge, two 250wt MH(20k) + 2 Atinic T5, and it is 36" high and 24" deep. I put the the guy on the bottom quarter or third of the tank, on a rock point towards the front (knowing to put it deeper and not directly under lights). It has since about doubled in size, but all the green coloring has completely left it, now brown/tan with pink eyes. I do not believe it is a flow issue, because the polyps at the eyes are extended frequently, and extend far during feeding. I of course do all my mineral additives daily and phosphate removers and what not and all my other colors are brightening up every day. And also by my testing, I think it is safe to assume my levels are spot on. So why is my mummy eye losing all of its color? the only way to do less lighting would be to literally cover it up. could it possibly need more? or not a lighting issue at all? any advice from people with experiance with this chalice would be a tremendous help. thank you for your time.

Here are the pictures of when I first got it and now. The orignal one was taken under more blue lighting, but I think you can still get the idea. sorry if it is fuzzy.

If your tank is truly 36" high and the coral is on the bottom third it might not be receiving enough light. Do you spot feed?

I spot feed sometimes, but judging by its growth i would think its getting more than enough food

Is it possible your tank could be too clean? I have a mini colony of mummy eye and I have it at about half way getting a lot of light. In my old tank which was SPS dominated it lost some color due to the water being too clean. Now since my water is a little dirtier it's nice and green.

hmmmm, interesting idea. I know of corals like elegance corals that grow well under those conditions, so that could be true. Although i usually hear of Chalices kept in with clean water sps.
