Anyone seen a space invader get a brown eye like this? I've had this for about a year now grown from a small frag and a few months ago its two main eyes in the center turned brown. All the other eyes around the edges are still yellow and the entire colony still seems health otherwise. The brown eyes still put out sweepers and feed. Any ideas on how to get these eyes to yellow up?
Nutrient levels have always been the same in the range of 1-3ppm NO3 and .02 - .10 PO4. Flow is low to moderate where this coral is at. Lighting never changed and is low / moderate at about 150 par.
