Echinopora

I suspect that the two Echino’s of the Chalice world get mixed up a fair bit. But as previously mentioned, the Echinopora group was probably the first chalice coral to make it into the hobby. Aside from Echinopora lamellosa, the genera is comprised of the following other species: Echinopora ashmorensis, Echinopora forskaliana, Echinopora fruticulosa, Echinopora gemmacea, Echinopora hirsutissima, Echinopora horrida, Echinopora mammiformis and Echinopora pacificus.
