Christmas tree rock care

[Jungle Blue]

Does anyone know if these are photosensitive? I have mine at the bottom of my tank, about 80 PAR, I saw someone mention they have theirs in 350 PAR. I know that have to be fed phytoplankton, but do they also need heavy light?

The worms themselves? No, they don't need light but will react to shadows briefly.
The Porites coral will need light though, ~200 PAR.
I bleached my first rock with too much light. All wormies and crabs still doing their thing
