Blue Devilfish · Macneill's Assessor
Predators & Oddballs
A unique Australian endemic with a deep royal blue body that often swims upside-down beneath ledges and overhangs. Blue assessors are peaceful, hardy, and completely reef-safe — an excellent choice for community reef tanks. They are mouth-brooders that can be bred in captivity and are increasingly available through Australian aquaculture.
