Colorado Sunburst Anemone or CSB Nem for short, Colorado Sunburst Anemones are some of the most rare and sought after anemones in the industry. They have 3 different color phases (color patterns) with the 3 color phases being red, yellow, and orange. All 3 start with a darker oral disc that is kind of a purple color and that fades into either red, yellow, or orange on the tentacles. We have seen these nems sell for as much as $1500 when they were introduced in the market.
