To clear this up, there is the Porcelain Crab, and the Porcelain Anemone Crab. Two different types completely, but both contain the word "Porcelain".
The only point from experience I am making is that you do not want to match the Porcelain Anemone Crab with a BTA as it is not the correct nem and the crab will cause the BTA to be very unhappy.
