I'm looking for advice on purple candy canes. I've had green, neon green, blueish candy canes and they've done very well, especially the neon green. Because of their success, I really wanted to add the variety of the purple with the green mouths, but they just don't seem to be doing well in the same environment. The neon green, especially, but also the other green and blue seem to put out their feeders at night and when there's food present, but the purple always look very thin and skeleton-like and I haven't seen much growth. Are they that different in the way they act? The pictures attached aren't mine, but I feel like they convey what I'm getting at. I've done a lot of research and I can't find anyone discussing the difference between these different candy cane corals...
