Blastomussa (Blastos for short) are a great addition for coral reef enthusiasts looking to add a low light large polyp stony coral (LPS) to their reef tank. The first time I saw them, I thought they looked like a corallimorph mushroom but they had a skeleton. Blastos are an uncommon coral in the reef aquarium hobby, but are found for sale more often now as a result of propagation. Blastomussa corals come in a variety of colors and sometimes dazzling patterns. The two main species of Blastomussa are the smaller structured merletti and the larger polyp wellsi. So long as they are provided modest lighting, low flow, and regular feeding, this LPS coral should thrive in your home aquarium.
