Dear Sergey,
This species seems to be one of group showing a distribution pattern from east Africa right around to Thailand. Another interesting point is the blue sponge both animals are on, although not so clear in the lower photo. I checked earlier messages and found one [message #2203] with a similar blue patch. Not totally convincing evidence, but it matches the similarly coloured C. geometrica which feeds on the bluish Aplysilla violacea. In that species the underside of the anterior mantle is a bright deep purple. In C. conchyliata the underside of the anterior mantle is also coloured purple, but there is often an orange or reddish band along the edge, which can be seen in your upper photo.
Best wishes,
Bill Rudman
