This.
Your "white" ones come in from Bali fairly regularly, people will recognize them if you post a pic in about a month or two, and your other two have about 3 different hobby names each. Corals don't have to be the most unique in the world just enjoy them.
Awesome. Can you please show. Me a link so I will know the common name of each. I have searched and searched and have not found them at all. Thanks again for your assistance and teaching so much about these amazing pieces
