Activity, rest, and lifespan
Active mainly at night, when it leaves the coral to feed. Daylight hours are spent resting close to shelter with very little movement.
Lifespan in the wild has not been documented; aquarium fish often live several years.

Pajama Cardinalfish reproduction
Pairs spawn among the coral; the female releases an egg mass that the male fertilises and holds in his mouth for about a week until the eggs hatch. The larvae drift before settling on the reef.
Males and females look alike and cannot be reliably told apart by sight. A brooding male shows a swollen jaw and throat.
