Ritter, how is that base of your purple stylo? Just wondering as I have one approaching that size. Mine is losing some color at the base, but still has good PE even where the color is washed. I tend to lose big colonies near the base when they get soccer ball size so I'm beginning to worry. Not stylo, but I lost 3 different BIG birdnest colonies and a pocci once the base became too shaded.
It has polyps but not colored like yours. If I frag a piece the part underneath colors up right away.
