Rare means there are few like it. I would have to agree, you have a rare clam. Maybe one of the rarest based on the definition. Seems like rare to people = super pretty. You guys just need better sources for corals as they aren't rare, just super pretty and you pay a lot.
Thanks for sharing. I wonder how it got this way and if ORA sees these on occasion. I wonder what the survival rate of something like this is.
