These rainbows are at the top of their game. The main polyp’s turn fluorescent red/ orange with flaming yellow mouths. The rainbow babies feature stunning green, orange, yellow, and red centers. Keep in lower light for best colors. This iconic acan has been woefully sold out for over a year now. After its debut and explosive popularity in 2012, our mother colonies sadly crashed. We only have a handful of polyps left. It may never be back in stock for us, but it will always hold a special place in our hearts.
