Red Branching Cyphastrea

Cyphastrea decadia

Cyphastrea is an easy to keep and fast growing SPS coral, requiring moderate to strong aquarium water movement combined with moderate lighting conditions. It is important to leave ample space between Cyphastrea and neighboring corals since it can grow very fast under ideal conditions and is aggressive towards other corals.

While much more forgiving of alkalinity swings than other SPS corals like Acropora and Montipora. One should aim to keep alkalinity stable as it will increase both the growth and colouration of Cyphastrea.

As with all SPS corals our recommendation is to focus on keeping Alkalinity stable. Many people struggle to keep healthy SPS as they aren’t paying enough attention to their alkalinity, or they are trying to hit a specific dKH. We are less focused on the dKH of the water and more interested in making sure that it hasn’t changed since yesterday. When trying to lower or raise the dKH of our systems we always aim to do it as slowly as possible.
