Peacock-tail Anemone Shrimp (Ancylocaris brevicarpalis) イソギンチャクカクレエビ also Clown Anemone Shrimp (size 2.5cm)
The Peacock-tail Anemone Shrimp live on anemones and soft corals. I think that this soft coral is Litophyton arboreum. The female Peacock-tail above is larger and has more spots. They both have the orange spots with black edges on the tail. Amami
The male Peacock-tail Anemone Shrimp above is smaller, more transparent and has fewer white spots. Amami
