概述
Laetacara flamannellus 是巴西阿马帕州沿海水系的小型慈鲷。背鳍基部深斑外侧的橙色环是重要识别特征,种名也与这圈火焰般的颜色有关。它可能曾被误以近亲名称出售。
分布与栖息地
已知来自阿马帕州东部沿海河流,分布记录位于 Amapá 与 Mazagão 一带之间,模式产地在马卡帕附近的 Curiaú 湖。
多数采集点是季节性淹水草地,常在约 30–50 cm 深的静水岸缘、莎草状植物间发现。当地草地通常在 1–6 月被淹。另有一个采集点为流动的小溪,说明所有记录并非都来自静水,但不能据此要求整个缸保持强流。
繁殖
根据同属鱼的习性,推测本种也可能在固定表面产卵并由双亲育幼。这仍是近亲推定,不能视作已经确认的本种繁殖流程。
补充说明
背鳍基部黑褐色斑外的橙环可与 Laetacara curviceps、Laetacara dorsigera 区分。背鳍中部还有一条黄色带;繁殖个体不呈后者那样的红腹,臀鳍基部也缺少前者的红紫区域。
可能曾以 Laetacara curviceps 流通的说法带有不确定性。购鱼时应核对完整鳍色、花纹与产地,避免仅因外形相似就沿用标签。

Overview
Laetacara flamannellus is a small cichlid from coastal Amapá, Brazil. An orange ring surrounding a dark spot at the dorsal-fin base is an important identification feature and inspired its flame-related name. It may occasionally have been sold under a relative's name.
Distribution & habitat
Known records span eastern coastal rivers of Amapá between the Amapá and Mazagão areas. The type locality is Lake Curiaú near Macapá.
Most specimens came from seasonally flooded grasslands, among sedge-like vegetation in still marginal water about 30–50 cm deep. These grasslands usually flood from January through June. One contrasting collection came from a flowing small stream: the records are not confined to still water, but this does not establish a need for strong aquarium currents.
Breeding
Substrate spawning with care by both parents is suggested by other members of the genus. This remains a comparative expectation rather than a confirmed breeding procedure for this species.
Notes
The orange ring around the dark dorsal-base spot separates it from Laetacara curviceps and Laetacara dorsigera. Other useful features include a yellow stripe along the middle of the dorsal fin, absence of the latter species' breeding red belly, and absence of the former's red-purple anal-base area.
Possible historical sales as Laetacara curviceps should be treated cautiously. Compare the complete fin pattern and provenance rather than accepting a label from superficial resemblance.
