Tucked into some Plakina sponge. Under a rock. Shallow subtidal.
Tucked into a rock with a little bit of Botrylloides. A few egg coils nearby. A different location to the previous group so it must be a good season.
~2 cm long
Shallow subtidal
G. castanea?
Happy to find this population still here. Four individuals, each with unique patterning. Two of each under separate rocks (1 & 2, and 3 & 4). They have grown quite a bit since being observed by @ltimmo. The yellow spots on the mantle seem to be a feature present on all individuals.
Looking through previous observations it seems these can take on the colours of their prey ascidian to an extent. With these being purplish and see:

Edit: G. castanea?
There are Spotties (Notolabrus celidotus) in the area, but I'm not confident enough to id it.
