no...
Hydnophora rigida
thats the name.. darn.. i racked my brain all after noon trying to remember that...
but yes, you are right it might be
Pavona sp also
The hydnophona has a tendancy to grow more in a branching patern, and the Pavona tends to form more plate like structures. by that i mean they are wide and thin, not plating like
Echinopora or a
M. Capricornus just more side branches..
i actually have kept both of these. there appearance can vary but in my specimens the overall structure was the same. the Hydnophora has a mean sting but mine never had long sweepers, where the Pavona has a men sting and very long sweepers, but seem to only let them out in defense not for feeding
