The Black Widow Cyphastrea is a fast growing encrusting coral that in my tank prefers dimmer light.  

It is an LPS coral (Large polyp stony) which looks surprisingly similar to an SPS coral at first glance.  

This coral is a beautiful addition as it comes with a dark base and contrasting bright red polyps.

Cyphastrea are found in a variety of different colourations, with most of them encrusting over the rocks work

This coral needs appropriate lighting and moderate flow to maintain optimum health.

In addition to this, it will also require the correct levels of Calcium, Alkalinity, and Magnesium along with various other trace elements found in natural seawater.

Additional feeding isn't required to maintain its health however it will feed on micro-plankton and very fine coral foods. 

Care Level - Moderate

Flow - Medium 

Lighting - Medium (mine prefers shady areas)

Temperament - Short stinging polyps 

Frags of this coral are 2cm and are glued to frag plugs
