SPS bubble gum digitata losing color and polyp extension

[Kasrift]

Replying to an old thread, but it was recommended as a similar thread. I have a BG digi that grows like a weed. I think high flow helps. I had it split due to my carelessness and mounted a second piece right in front of my Nero 3 and it doesn't care at all.

Did the coral make a come back? If so what was it?
