Pteraeolidia ianthina has fan-like (like fingers on a hand splayed out) projections on each of its cerata. These don't seem to be present on the species photographed. The cerata look more like the shape of those on Spurilla macleayi although it does not match in other ways.

It's also much lighter in colour, but I thought that was partly because it's a baby, and there are big colour variations in the adults anyway

This is certainly a juvenile P. ianthina
