Dear Valda,
Your mention of Mexichromis reminds me I have some Mexichromis photos of yours to sort out. This animal though is not Mexichromis. It is Chromodoris aspersa. Sometimes you find individuals without the yellow/orange mantle border but otherwise they are identical anatomically. It does not seem to be a geographic thing because I have found pale ones in Tanzania and eastern Australia.

One good colour feature of this species is the washy or diffuse ring of purple that surrounds each purple spot [see inset].
Best wishes,
Bill Rudman.
