Neotropical cichlid possesses territorial aggression which explains their success as alien species that pose threats to local fauna. The feeding ecology of Midas cichlid, species outside its native range had never been fully understood. We aim to determine the stomach content, length-weight relationship and condition factor of this non-native species in one of the agroecosystems in Malaysia. The fish was collected using a cast net, and the guts were dissected. The stomach content ( = 35) revealed Midas cichlids feed on a wide array of preys including fish, amphibian and gastropod. The -value is 2.60 (negative allometric growth) and the relative condition factor, Kn is 1.04. This result represents an initial study on the feeding aspect of this cichlid. Subsequent and continued researches are needed to evaluate the feeding behaviour and prey preferences of this species in its introduced range.
新热带丽鱼具有领地攻击性，这解释了它们作为外来物种取得成功并对当地动物群构成威胁的原因。米达斯丽鱼（一种分布在其原生范围之外的物种）的摄食生态从未得到充分了解。我们旨在确定这种非本地物种在马来西亚一个农业生态系统中的胃内容物、体长-体重关系和条件因子。使用撒网收集鱼类，并解剖其内脏。胃内容物分析（n = 35）显示，米达斯丽鱼以包括鱼类、两栖动物和腹足类动物在内的多种猎物为食。b值为2.60（负异速生长），相对条件因子Kn为1.04。这一结果代表了对这种丽鱼摄食方面的初步研究。需要后续持续的研究来评估该物种在引入范围内的摄食行为和猎物偏好。
