Blue Cespitularia - Cespitularia sp.

Cespitularia is closely related and similar to the more common Xenia but is far less common and more difficult to keep. Unfortunately these corals do not ship well, so getting a healthy specimen can be very difficult. Some colonies are known to grow to nuisance levels at times then die back for no apparent reason and different aquarists have different experiences and opinions at what may cause Cespitularia to grow or decline rapidly.

These corals like medium to strong lighting, and medium to strong water movement. The colonies can benefit from filter-feeder supplements and iodine supplements and generally do not tolerate high nitrate levels. They can be found in shades of blue (commonly called "Blue Xenia"), green or pink.
