Unknown nudibranch

Unknown tiny (maximum 1 cm in length) nudibranch found in a mangrove environment in the wakatobi marine national park. They resemble anenomes. I'm pretty sure that the green specs in the tentacles/appendages are endosymbiotic algae (zooxanthellae). Aside from that the appendages are translucent with white tips. You can see their spiral shaped egg-cases in thesecond and third picture.
