Occur in groups around coral bommies . In Japan, the breeding season is from June to September. Breeding pairs set up territory which is mostly defended by the female . Mouthbrooding is done by the male parents some of which resort to partial egg cannibalism probably to adjust the brood size to their buccal capacity . Nocturnal species, but courtship and spawning takes place during day .

🥚 Reproduction

Clutches of eggs from a single female are mouthbrooded by males . Distinct pairing (obligate monogamy) during courtship and spawning . Multiple spawner with 10-19 days interval between matings . Females attack conspecifics during courtship . The operational sex ratio is male biased all throughout the breeding season primarily due to a higher mortality in females, thus sex-role reversal is not predicted for this species .
