[nogascans]

Could I please get an ID and recommendations on placement and feeding/care of this SPS in attached picture? I have labeled/mislabeled?? it as favia. In other picture og entire tank, it is located at center and low in tank.

Sincerely,

David

Looks like Australomussa (sorry for the spelling)

That's a Pectinia; there seems to have been an influx of that particular color morph lately. Just for reference it is actually an LPS and has requirements similar to a lot of chalices; your placement in the tank sounds just about right. It doesn't have to be fed, but will grow quicker if occasionally offered small meaty bits. Mysis, brine, even small pellets would work just fine.
