Bi Color Hammer

An intermediate large-polyp stony coral (Euphyllia) with green, hammer-shaped tentacles tipped in purple. It does best with stable alkalinity and calcium, moderate light, and moderate indirect flow that lets the tentacles sway without tearing. Feed small meaty foods or LPS pellets once or twice a week for best growth and color. Give it room — many LPS extend sweeper tentacles at night. Light: Moderate (about 100–200 PAR). Flow: Moderate, indirect. Placement: Bottom to middle rockwork or sand bed. Space: About 6 inches from neighbors.
