Mottled Jawfish
Most likely: Opistognathus maxillosusThe jawfish excavates their burrows in protected areas of coral reefs in the sand and rubble, lining the entrance with pieces of stone and coral bits. They sit in the burrows with head exposed unless feeling threatened, then will retreat completely. It's the jawfish male that broods the young by them in his mouth.
