So i purchased a few corals the other day. Im very new to reefing and i have a 13.5g nano set up for my room. The shop i got them from was very informative although I seem to have forgotten what he said the name of this coral was can you guys help me please? So i remember him telling me about the obvious zoa the one all by itself is supposed to be galxea i believe they call it. Can anyone give some clarity to if this is correct and what the one im unsure about is exactly please??
