Yellow Assessor
Assessor flavissimus
Yellow Devilfish
The golden-yellow cousin of the blue assessor, sharing its unique upside-down swimming behaviour and cave-dwelling habits. Yellow assessors are equally hardy, peaceful, and reef-safe, making them a standout choice for Australian reefers wanting a distinctive, locally sourced fish. Like the blue assessor, they are mouth-brooders and increasingly captive-bred.
