概述
Oreichthys sp. 'Myanmar Redfin' 是可能尚未描述的缅甸小型鱼，成年雄鱼背鳍延长，带黄色至橙色，而没有明显黑斑。它摄食较胆怯，需要安静环境和有遮蔽的小群，而非热闹的综合缸。
分布与栖息地
可能来自缅甸北部伊洛瓦底江水系，具体地点尚未确认。Yuzana Myaing 村附近、密支那至 Myitzon 公路旁的 Hpa Lap 溪，是被认为较可能的采集地，不应当作已确认唯一产地。
它可能偏好清澈、缓流的小支流和源头河段，岸边植物浓密或悬垂，这仍主要是参照同属鱼的环境推测。
饲养环境
用水草、沉木布置丰富遮蔽，加浮水植物减光，落叶提供自然感。水流轻柔，底床尽量柔软，以适应本属下颌细小感觉结构参与的觅食方式。
造景应多处阻断视线，防止弱势鱼一直暴露在强势个体面前。
食性与喂食
能接受合适粒径的干粮，但每天仍宜补充细小活饵或冷冻水蚤、丰年虾等。由于容易害羞和迟疑进食，需确认食物是否实际被它吃到，而不是被别的鱼抢完。
习性与混养
较大或过于活跃的同伴会造成压力。小型温和鲤科鱼较合适，一些体型小的脂鲤、底层鲶鱼可能相容，但仍需观察。
宜至少八条，形成有等级的松散群体。雄鱼会展示、较量，单养、群体太少或环境拥挤时可能变得退缩，弱势鱼也可能长期受欺压。数量和遮蔽要同时满足。
雌雄区分
雄鱼稍大，体色及鳍色更强，背鳍延长并呈淡黄，强势个体背鳍可浸染橙色。
繁殖
尚无可采用的人工繁殖记录。
补充说明
常被混用近似种名称出售。成年雄鱼背鳍无暗斑，以及尾柄大而清晰的黑斑，是较有用的区别。未定种代号不应被误当成已经正式命名的种加词。

Overview
Possibly undescribed, Oreichthys sp. 'Myanmar Redfin' develops an elongated yellow to orange male dorsal fin without a prominent dark mark. Hesitant feeding favors a quiet, sheltered group over a busy general community.
Distribution & habitat
Northern Myanmar's Irrawaddy basin is the presumed origin, but the locality remains unconfirmed. Hpa Lap stream near Yuzana Myaing, off the Myitkyina–Myitzon road, is a likely candidate rather than a verified exclusive collection site.
Clear, slow tributaries or headwater sections with dense bankside vegetation are the suspected habitat, largely by comparison with related fishes.
Aquarium setup
Combine plants and wood for numerous refuges, adding floating shade and optional leaves. Keep flow gentle and favor a soft bottom for the genus's foraging method involving fine lower-jaw sensory structures.
Break sight lines in several places so subordinates are not continually exposed to dominant fish.
Diet & feeding
Suitable dry food is accepted, but provide daily tiny live or frozen water fleas, Artemia, and similar items. Shy feeding makes it essential to check that the fish gets food before companions take it.
Behaviour & compatibility
Large or boisterous companions can intimidate it. Small peaceful cyprinids are better choices; some small characins and bottom catfishes may work, with observation.
Maintain at least eight in a loose hierarchy-based group. Males display and spar. Isolation, too few companions, or crowding can promote withdrawal and persistent bullying, so both group size and cover matter.
Sexual dimorphism
Males are slightly larger and more colorful. Their extended dorsal fin is yellowish, becoming suffused with orange in dominant individuals.
Breeding
No usable aquarium breeding record is available.
Notes
Similar-species names are often applied in trade. The adult male's unmarked dorsal fin and the large distinct tail-base blotch are useful clues. The provisional designation should not be mistaken for a formally established species name.
