i have a mini colony of zoas i got a while back that were just no names. when i got them they were solid purple, over the past two months they have went from solid to purple to purple with brownish colored skirt to purple, brown skirt and a pail yellowish white ring around the center. I have been googling all day about them re gaining their color which is very similar to the way mine have done. I was just curious if anybody has had them before and witnessed them gaining color back or have any intelligence on my situation? i wish i could post pics but dont have a good enough camera to capture the detail.
