Update. After removing the extra anacropora and the huge birdsnest, I'm noticing everything across the board is looking healthier. A few of my larger acros are starting to get some color back in their tissue, my forest fire digi is getting back it's gree base color that was completely missing, and everything else is looking just a little brighter. The hypothesis was that the fast growing corals we're stripping the water and starving their neighbors and I think It was spot on.
