I think you have two different species here. The large animal is what I am calling Chromodoris cf. africana and I am pretty sure the small animal is Chromodoris cf. strigata. Unfortunately that means you haven't a 'real' name for either of them, but it is a useful bit of information to help sort them out.
Of particular interest is that both these animals seem to be feeding - or showing great interest - in the bluish-grey sponge they have their heads on, which I am pretty sure is a dysideid. Interestingly this is an unusual choice for a species of Chromodoris but we already have a record C. cf. strigata [message #18512] feeding on a similar dysideid.
