The Blue Blanquillo Tilefish is a sand tilefish native to reefs of the Indo-Pacific region. It reaches 45 cm long and
can vary the intensity of its blue colour.
It is carnivorous, eating worms, crustaceans, sea urchins and small fish. Mainly marine, it is known
to inhabit brackish estuary waters in Papua New Guinea.
The juvenile Blue Blanquillo looks initially somewhat like juveniles of the Ringed Slender Wrasse (Hologymnosus annulatus),
with a thick black underside from tail to snout, a pale top and a shorter, less pointed face than the adult. The subadult above still has a much
shorter face than the thick-lipped adult but the black lateral line has narrowed although it is still from tail to snout. Also the squiggly lines
have yet to appear on the upper back.
