yep. Goniopora for sure.
Maybe G. norfolkensis, but we would need a macro of the polips to be sure. It could also be a G. stokesi, which is much more complicated to keep
In order to thrive they need turbid water and lots of zooplancton and fitoplancton to eat.
It´s important to have a DSB, refugium and low skimming and it´s a must not to have mechanical filtration
Hope this helps
