Blastomussa are one of the few corals that appreciate very dim light. We have seen them expand better and take on much more vibrant colors under subdued lighting while struggling greatly under bright lights. When overexposed portions of their polyp may become unnaturally inflated or even develop bubbles inside their flesh. If you have a reef tank with modest lighting, Blastomussa may be right up your alley.

Moderate water movement is recommended. Blastomussa do not seem particularly picky on the type of flow they receive. We have kept them in both low and strong flow reef aquariums without significant differences in health. 

The Blastomussa genus, like other LPS corals, have developed several feeding strategies. Through a symbiotic relationship with a marine algae, known as zooxanthellae, they receive some of their nutrients. They also capture planktonic organisms, food particles from the water column, and can absorb dissolved organic matter. This coral also benefits from the addition of calcium, strontium, and other trace elements to the water column.
