These nudibranchs appear to be what you call Armina sp. 7. Armina are common on sandy slopes and rubble bottoms in Timor, but usually we see them eating sea pens. In this case, the two Armina were eating a soft coral, Dendronephthya.

Thanks for this observation. We don't know enough about the biology of the arminids to know whether some species are exclusively feeding on sea pens and others on soft corals such as Dendronepthya.
