So the first 2 pictures show almost a white flower or something taking over the coral.
The 3rd and 4th picture are some kind of red/brown algae. It looks like it is growing arms.
Right beneath the polyp i am seeing this black tentacle looking growth.
This is the same red/brown algae as before, but it has attached to the sea urchin.
All of my corals have come from WWC and were dipped twice. None of them come off with blasting with a turkey baster too much. I can pry the red/brown off somewhat. If anyone can help ID these and recommend a treatment, that would be a great help.
