概述
Barilius malabaricus 来自印度西南部，体侧带蓝绿色圆形或椭圆形斑点，背鳍和臀鳍边缘宽而呈橙色。它游速快、进食积极，需要大面积泳道与稳定清洁的水体。
分布与栖息地
可靠记录来自喀拉拉邦的帕亚斯维尼河及瓦拉帕塔南河水系，可能还分布于卡纳塔克邦南部及喀拉拉邦北部的其他河流。
其自然环境推测为富氧、流速中等至快的溪河，底部有砾石、大石和裸露基岩；这一栖息地描述仍需保留推测性质。
饲养环境
缸底至少 150 × 60 cm。用砂砾、大小石块和根枝组成流水缸环境，布景应给连续游动留足空间，水草可选择能固定于石木上的耐受种类。
保持成熟过滤和良好溶氧，避免有机废物积累。每周换水 30%–50%，不宜放入新建、尚未稳定的缸。缸盖要严密，防止跳出。
食性与喂食
同属鱼通常在水面摄食昆虫。人工食谱可安排优质干粮，加上红虫、丰年虾、切碎蚯蚓等活饵和冷冻饵。果蝇与小蟋蟀也可使用，但应先充分喂养再投喂。
习性与混养
不适合普通小型混养缸，慢游或胆怯的鱼可能被抢食及压制，体型过小者有被捕食风险。应选择同样健壮、大小接近且适应流水的伙伴。
至少 5 尾同养，留意群体等级。少量两三尾会让追逐集中于弱势鱼，单养则可能把攻击转向外形相似的伙伴。
雌雄区分
成年雌鱼一般颜色较淡、体型稍大且更厚实，抱卵时尤其明显。
补充说明
本种在恢复有效种地位前，曾以其他同属鱼名称或带“橙鳍”的商品标签流通。体侧斑点形态有助于区别，旧贸易标签不足以确定身份。尚无可整理的人工繁殖记录。

Overview
Blue-green rounded flank spots and broad orange borders on the dorsal and anal fins characterize Barilius malabaricus. This southwestern Indian fish is a rapid swimmer and energetic feeder that needs open space and stable, clean water.
Distribution & habitat
Certain records come from Kerala's Payaswini and Vallapattanam systems. A wider range across northern Kerala and southern Karnataka is considered possible.
The proposed habitat consists of well-oxygenated streams and rivers with moderate to fast current over gravel, boulders, and exposed rock. This ecological description remains probable rather than fully established.
Aquarium setup
Allow at least a 150 by 60 cm footprint. Build a river-style setting from sand, gravel, differently sized stones, and roots while preserving long swimming lanes. Hardy attached plants may be secured to the decor.
Maintain established biological filtration, good oxygenation, and freedom from accumulated organic waste. Weekly changes of 30–50% are recommended. An immature aquarium is unsuitable, and the cover must fit securely to prevent escapes.
Diet & feeding
Insect capture at the surface is described for the genus as a whole. In captivity, supplement good dry foods with live or frozen bloodworms, brine shrimp, chopped earthworms, and comparable items. Fruit flies or small crickets should be well fed before being offered.
Behaviour & compatibility
Ordinary small community arrangements are unsuitable. Slow or timid fish can lose out at feeding time, and very small tankmates risk predation. Select sturdy, similarly sized companions suited to flowing water.
Keep a minimum of five conspecifics. A hierarchy develops, with tiny groups exposing weaker fish to concentrated harassment; solitary fish may instead challenge similar-looking neighbors.
Sexual dimorphism
Adult females generally have less vivid color and become slightly larger and thicker than males, especially when carrying eggs.
Notes
Before its revalidation, this fish circulated under other congeneric names or orange-fin trade labels. Flank spot shape helps distinguish it, but an old sales name is insufficient for identification. Captive breeding details remain unreported.
