Been growing this from a small frag since late 2010 or early 2011. Fragged a couple times. Almost 4" across. Some of the polyps along the edge are getting cool red/blue/purplish stripes. My favorite acan echinata of all time. Has a green growth rim similar to a chalice but you can't see it in the pics. It's like the rainbow chalice of acan echinatas.
