Changes in the levels of activities by parental female and male convict cichlids were studied over three successive reproductive episodes and within each episode. No evidence was found for behavioural maturation independent of experience. With successive episodes, young survived for longer times, nests were cleaner, males ate less and females more, and males became more aggressive while females focused more on the nest. Within an episode there were also marked variations in activities by each sex. Reproductive behaviour is therefore open in a number of respects both within and across episodes to environmental inputs.
在连续三个繁殖期以及每个繁殖期内，对亲代雌性和雄性 convict 丽鱼的活动水平变化进行了研究。未发现行为成熟独立于经验的证据。随着繁殖期的延续，幼鱼存活时间更长，巢穴更清洁，雄性进食减少而雌性进食增加，雄性变得更具攻击性，而雌性则更专注于巢穴。在一个繁殖期内，两性的活动也存在显著差异。因此，繁殖行为在多个方面，无论是在繁殖期内还是跨繁殖期，都对环境输入开放。
