The Pearlscales continue to be very popular. One is more fantail in shape, one is much like an orange or ping pong ball in shape and the third is an Oranda / Crown Pearlscale (Hamanishiki). This unique scale type and modified chest size was developed in China. The recessive trait is in both nacreous and metallic fish in a variety of colors. While common with importers, there are very few line breeders in North America. Presently the ping pong ball shape is currently most common.
