Yellow Assessor

Yellow Assessors are carnivorous and prefer small live or frozen foods such as brine shrimp, mysis shrimp, copepods, and small crustaceans. Feed small portions once daily, offering only what they can consume in a few minutes. They may also accept high-quality carnivore pellets and frozen foods, but live prey encourages natural hunting behavior.

Yellow Assessors are peaceful, shy fish that spend much of their time hovering near caves, crevices, and overhangs where they characteristically swim upside down along the undersides of rocks and structures. They are primarily nocturnal and crepuscular, becoming more active during low-light periods. They are solitary or occur in pairs and do not school, preferring to stay close to shelter.

Breeding Yellow Assessors in captivity is difficult and rarely achieved in home aquariums. They require specific cave structures, stable water conditions, and may be territorial during spawning. Little is documented about their reproductive behavior in captivity, making successful breeding a significant challenge even for experienced aquarists.
