Got it from the swap here. Cannot remember the name. It started wee small with a very pretty red mouth. It has since changed, due to lighting I'm sure. I've got it inna corner under the over flow box because I remember being told lower light. LMK.

Hmm I have something VERY similar looking in my tank that was identified as a lobophyllia. strange.
A lobo can have a similar structure but the polyps are much larger. Typically a lobo polyp is several inches across. While a favia might reach an inch across.
