Appearance Description
Green Star Polyps form encrusting mats with numerous small polyp heads that are bright green or yellow-green with distinctive radial tentacles. Individual polyps extend 0.5–1 inch when feeding and retract into the base when disturbed.
Additional Notes
Nearly indestructible. Thrives in almost any light from low to high and accepts a wide range of flow conditions. Prefers moderate flow so the polyps stay extended without tearing. Nutrients can be low or high and it will still grow. The real care requirement is controlling it. Keep it on an island rock or a back wall you actually want covered. Scrape or chip the mat back when needed. If it touches another rock, it will spread without hesitation. Looks fantastic when isolated and controlled, looks like a hostile takeover when not.
