Amphiprion perideraion are monogamous fish where only two of the representatives of a group are actually involved in the mating. The female and dominant male are strictly monogamous. When the female dies, the largest male undergoes a sex change and becomes the mating female. After this, the second largest male actively becomes involved in mating.
In spawning, male A. ocellaris chase females, passing over the nest. With each pass, the female lays a line of eggs which adhere to the rock surface. The male then fertilizes the eggs and protects them from predators.
Mating System: monogamous
Amphiprion perideraion spawn several times between April and August, but sometimes as early as February, depending on the conditions. In this species, the largest fish is always the female and the second largest fish is always the male. Fish are male first until the female dies (protandrous). During a year, the pair may produce between 2000 and 4000 eggs. Both males and females reach maturity between 1.75 and 1.83 years of age.
While little research has actually been done on the reproductive mechanisms of A. perideraion, a similar species Ampiprion ocellaris showed several interesting reproductive mechanisms. Females control males through agression and chase away other females. Dominant males build a nest on a bare rock face near an anemone. Courtship behavior in A. ocellaris includes the extension of spines, biting, and chasing.
Breeding interval: Amphiprion perideraion will breed several times a year with no obvious peak season.
Breeding season: They breed between April and August.
Range number of offspring: 2000 to 4000.
Range age at sexual or reproductive maturity (female): 1.75 to 1.83 years.
Range age at sexual or reproductive maturity (male): 1.75 to 1.83 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sequential hermaphrodite (Protandrous ); sexual ; fertilization (External ); oviparous
Male Amphiprion perideraion protect the developing eggs while they are attached to the substrate just outside of the host anemone, for about 6 to 8 days. When the eggs hatch, the larvae leave the host anemone.
Parental Investment: pre-fertilization (Provisioning); pre-hatching/birth (Protecting: Male)
