Finding their name, if they were named. Would be very hard. Favia family is very large and look alike. One week it is named "a" next week it is named "b". To me first looks like a favites and the second could be a prism favia.
Is a Goniastrea (you can tell my the even circular corallites and it is not a favites because they do not share a wall you can clearly see a "peak" in between where each wall surrounding the corallites merge)
