Assessor randalli
Assessor randalli, commonly called Randall's assessor, is a diminutive marine fish reaching only about 4 cm in length. It inhabits coral reef flats and lagoon edges where it darts among rubble and algae, making it a curiosity for snorkelers rather than a traditional sport fish. Though not sought after for food, its vibrant colors attract aquarium enthusiasts.
