Back from the dead

[jb1974]

I have had something like this happen as well. I bought a purple humilis colony about 7 months ago. It bleached within a month and so I placed it on the bottom of my tank. I thought it was a goner, but left it there anyhow. I even transferred it over to my new tankwhen I upgraded. In the past 3 months it has slowly been regaining color. I have no idea what prompted it to get it's zoox back or what it was subsisting on all those months to keep it alive, or even why it bleached in the first place...weird...the coral started regaining it's zoox on one side and it slowly crept over to the other, it's about halfway on its way to full recovery now. I always thought that when bleaching corals recovered it was quick, but now I know it can take months in some cases....
