finger leather coral isn't green any more

[al404]

I bought about 10 months ago a finger leather coral that was green, not very much green but not like it looks today

After a some months it split into 2 pieces and I set them in different points

Now it looks like this

In pictures where there are more then one is the one in the middle

what is you lighting....and also your parameters....they like good lighting /flow....also if your nitrates are high...they might brown out...

Has there been any changes to your lighting within the last 10 months? From the pictures above it almost looks like there under a 10K bulb or something similar. Increasing the blue spectrum might bring out the green again.

Sorry this is a bit off topic but... how do you get pictures to show up full size instead of links or thumbnails?

Based on how everything looks, I also think the issue is with the lighting

Looks like that light has more white bulbs than blue bulbs and is described as "giving you a nice crisp white worthy of most marine aquariums." Instead of adding a light I would try adjusting the white:blue ratio. My light has more white than blue and my Montipora is also significantly more brown than it used to be.
