A relative of the acropora, the anacropora is much like a cross between a branching monti and an acropora. The key difference is that the anacropora does not have axial corallites like acropora (the polyps on the tip of each branch).
The Green Goblin is an extremely bright yellow/green and a very fast grower. Keep this coral under the same conditions as a high growth acropora, high lighting and flow.
