“…One interesting hypothesis is that variation in response could be due to variation in personality traits (defined as inter-individual differences in behavior that are consistent over time and across contexts 54 ) of the individuals being tested. Previous studies have demonstrated the existence of personality traits (e.g., boldness, aggressiveness, shyness, sociability, and parenting behaviors) in A. percula 55 , 56 and its sister species A. ocellaris 57 . It was not possible for us to test this idea, or alternative explanations for the variation in response, with our data.…”

Ecological and social constraints combine to promote evolution of non-breeding strategies in clownfish

Individuals that forgo their own reproduction in animal societies represent an evolutionary paradox because it is not immediately apparent how natural selection can preserve the genes that underlie non-breeding strategies. Cooperative breeding theory provides a solution to the paradox: non-breeders benefit by helping relatives and/or inheriting breeding positions; non-breeders do not disperse to breed elsewhere because of ecological constraints. However, the question of why non-breeders do not contest to breed within their group has rarely been addressed. Here, we use a wild population of clownfish (Amphiprion percula), where non-breeders wait peacefully for years to inherit breeding positions, to show non-breeders will disperse when ecological constraints (risk of mortality during dispersal) are experimentally weakened. In addition, we show non-breeders will contest when social constraints (risk of eviction during contest) are experimentally relaxed. Our results show it is the combination of ecological and social constraints that promote the evolution of non-breeding strategies. The findings highlight parallels between, and potential for fruitful exchange between, cooperative breeding theory and economic bargaining theory: individuals will forgo their own reproduction and wait peacefully to inherit breeding positions (engage in cooperative options) when there are harsh ecological constraints (poor outside options) and harsh social constraints (poor inside options).

Interspecific hybridization of Orange Clownfish Amphiprion percula (sire) and Clown Anemonefish A. ocellaris (dam) was displayed in successful pair formations within 4 months of rearing. Spawning mostly occurred at midday after a week of courtship. Incubation of eggs took 7-8 d, with the male showing the most parental care and the female sharing less time with the eggs. The hybrid embryo underwent 26 stages of cleavage to develop into a larva. The length of newly hatched hybrid larvae was significantly different from that of purebred Clown Anemonefish larvae and purebred Orange Clownfish larvae. Spawning frequency of interspecific pairs was three times in a month, similar to that of the Orange Clownfish intraspecific pair, whereas the Clown Anemonefish pair spawned two times in a month. Fecundity rate (60-370 eggs/spawn) significantly increased from the first spawn to the end of an annual cycle. Results of the present study indicate that interspecific pair formation and spawning are like those of other domesticated clownfishes. Essential reproductive parameters, such as fertilization and hatching rate, were low, but the survival rate of F 1 hybrids was similar to that of other clownfishes. The precise selection of closely related species, sexual maturation, and generating pairs are essential to initiate crossbreeding technology at commercial hatcheries.

“…Activity is a consistent behavioural trait in anemonefish symbionts and a useful measure to monitor acclimation (Wong et al, ). To characterise whether the behaviour pattern of A. ocellaris changed when they encountered different anemone hosts, the fish in each tank were videotaped on the third day after their introduction into the experimental system.…”

In this study, we investigated the host choice of naïve Amphiprion ocellaris, a specialist, at two different stages of development (newly settling juveniles and post‐settlement juveniles). The fish were exposed to their natural and unnatural host species in the laboratory and their fitness was assessed in terms of activity and growth rate. Newly settling juveniles exhibited little host preference, while post‐settlement juveniles immediately associated with their most common host in the wild. The analysis of fish activity confirmed that A. ocellaris is diurnal; they are most active in the morning, less at midday and barely move at night. The average travelling distance of juveniles was shorter in the groups living with their natural host, increasing in the groups living with an unnatural host and was highest in groups that did not become associated with any other unnatural host species. Post‐settlement juveniles living with the natural host species grew better than those living with unnatural hosts or without anemone contact. These results suggest that the welfare of A. ocellaris in captivity will be optimized by keeping them with their natural anemone host species, although more generalist Amphiprion species may survive in association with other hosts.
