概述
Devario apogon 是来自云南大盈江水系的小型鱼，没有须和侧线。体前侧有细而不显眼的竖纹，后半身带宽阔并逐渐收窄的横带，是辨识时可关注的组合。
分布与栖息地
已知产地均位于中国云南西南部的大盈江流域，涉及腾冲、梁河及盈江一带；缅甸东北部也可能存在。栖地相当多样，从大河、支流、溪流到沟渠都有，水可清澈或浑浊，底部可为泥、沙、砾石和裸露岩床。它曾在农田附近溪流及路边缓流水道被发现，显示一定适应能力。
饲养环境
可尝试以成熟、维护良好的溪流式水族箱饲养，用圆滑石块、沙砾、沉木和附生水草构成环境。适度水流与较高溶氧可能较合适，每周换水约三成至一半，避免污染积累。缸盖必须严密，防止跳跃。上述布置属于基于近缘鱼的尝试方向，仍需观察个体适应情况。
食性与喂食
野外很可能主要吃昆虫及其幼虫，人工环境可能不难开口。可尝试尺寸合适的优质干粮，同时轮换红虫、水蚤和丰年虾等活饵或冷冻饵，注意确认实际摄食。
习性与混养
性情尚未充分确认，推测不太具有攻击性，但不能据此保证任意混养都安全。可参考同属鱼至少六尾群养，并留意群内和对同伴的实际互动。
雌雄区分
成熟雌鱼通常更大、腹部更圆、颜色较淡。繁殖状态的雌雄都会出现橙红色，尤其体下部明显；雄鱼的深色花纹同时更浓。
补充说明
无须、无侧线及前竖纹后横带的组合比单纯观察体色更有鉴别意义。与近似种比较时，应考虑幼鱼或雌鱼的斑纹可能较淡。

Overview
Devario apogon is a small fish from Yunnan's Daying River system. It has neither barbels nor a lateral line. Faint narrow bars toward the front and a broad, tapering band behind them provide useful identification clues.
Distribution & habitat
All confirmed localities lie within the Daying drainage of southwestern Yunnan, including the Tengchong, Lianghe and Yingjiang areas. Occurrence in northeastern Myanmar is possible. The fish uses rivers, tributaries, streams and even ditches, across clear or turbid water and bottoms ranging from mud to exposed rock. Records near cultivated land and in roadside waters suggest considerable adaptability.
Aquarium setup
A well-established stream-style aquarium is a reasonable approach to try, using rounded stones, sand, gravel, wood and attached plants. Moderate circulation and high oxygen availability are likely appropriate. Regular changes of about a third to half of the water should limit pollution, and a close-fitting lid prevents jumping. These suggestions draw on related fishes and require observation of how the actual fish settle.
Diet & feeding
Insects and larvae are considered the most likely natural prey. Captive fish are expected to accept a varied menu, but intake should be checked. Offer suitable dry food alongside small live or frozen invertebrates.
Behaviour & compatibility
Temperament has not been well established. Aggression is thought unlikely, rather than ruled out. A group of at least six is suggested by comparison with relatives, with ongoing observation of both internal interactions and any tankmates.
Sexual dimorphism
Females are expected to be slightly larger, fuller-bellied and paler. Both sexes can develop orange-red coloration during reproductive condition, especially below, while males also intensify the dark markings.
Notes
The combination of absent barbels, absent lateral line and contrasting front and rear patterning is more useful than body color alone. Faint markings in younger fish or females may complicate comparison with similar species.
