I believe all Caribbean hard corals are illegal to collect or sell, certainly thats the case for the ESA listed ones.
Its pretty silly really. Long after Caribbean reefs finish collapsing, hobbyists will still be propagating coral genotypes that have been in the hobby for many decades. If the extremists hadnt pushed for zero tolerance bans, the surviving corals could include some Caribbean ones.
We can bulldoze acres of living reefs for coastal development but if you take a coral from the ocean and put it in an aquarium, thats illegal. Good stuff!
(want to really see how dumb it is? Collection and sales of the sun coral Tubastrea coccinea from the Caribbean is illegal. This is an invasive species. Managers throughout the Caribbean and Gulf are charged with collecting and destroying it. But collect some and sell it? Illegal)
