概述
Betta midas 体形粗壮，鳃盖、腹部和身体有金色亮鳞。它曾以近缘种名出售，图片标签也常混淆，饲养和繁殖记录都应先确认对象。
分布与栖息地
已知来自印度尼西亚婆罗洲西加里曼丹卡普阿斯河下游安戎岸附近，三发河及马来西亚沙捞越最西部也可能有分布。明确采集记录包括流经完整或残存泥炭沼泽森林的黑水河流，水呈酸性。
饲养环境
一对或小群至少需要约 80 × 30 cm 的缸底面积。用沉木、枝条、陶盆或短管安排阴暗藏身处，落叶提供遮蔽和微生物，也可用裸底方便维护。
采用弱光、耐阴植物及浮水植物，成熟海绵过滤缓缓循环。需要很软的酸性水，碳酸盐硬度很低，必要时使用可靠软水来源。缸盖要可靠，本种善跳；水面上保留潮湿空气层和上浮呼吸空间。
食性与喂食
自然可能以昆虫和其他小型无脊椎动物为主。适应后通常能接受干粮，仍应规律搭配水蚤、丰年虾、红虫等活饵或冷冻饵。小昆虫可先喂饱再投喂，控制总量，避免过肥。
习性与混养
可成对或组群，但更适合单种缸，或与极温和且条件相符的伙伴相处。大型、活跃和抢食强的鱼容易使它退缩，普通混养缸不应成为默认选择。
雌雄区分
成熟雄鱼体色纹理更强，头较宽，各鳍延伸更明显。
补充说明
本种曾被当作相似近亲（Betta anabatoides）交易，许多旧图片沿用错误标签。金色亮鳞、从黑色下唇经眼延至鳃盖的黑纹，以及带深色横纹和延长中央鳍条的尾鳍，可结合来源作为辨识线索。不能只按图片标题确认身份。

Overview
Betta midas is a stout fish with gold iridescence on the gill covers, belly, and body. Historical sales and image labels often confuse it with a close relative, so identity should be checked before applying species-specific records.
Distribution & habitat
Confirmed records come from the lower Kapuas drainage near Anjungan in West Kalimantan, Indonesian Borneo. Occurrence in the Sambas system and far western Sarawak remains possible. Documented collections include an acidic blackwater river flowing through intact and remnant peat-swamp forest.
Aquarium setup
Allow at least an 80 × 30 cm footprint for a pair or small group. Use wood, branches, pots, or short tubes to create shaded retreats. Leaves add cover and microorganisms; a bare floor can simplify cleaning.
Subdued illumination, shade-tolerant plants, floating vegetation, and gently running mature sponge filtration suit the setting. Very soft acidic water with little carbonate hardness may require a dependable soft-water supply. The fish jumps effectively, so secure the lid while retaining humid air and surface access.
Diet & feeding
Insects and other small invertebrates are considered probable natural foods. Established fish usually learn to eat dry products, supplemented regularly with water fleas, Artemia, bloodworms, and other live or frozen items. Small feeder insects can be fed beforehand. Avoid excessive portions.
Behaviour & compatibility
Pairs and groups are possible, but dedicated housing or exceptionally gentle companions with matching conditions is preferable. Large, energetic, or competitive feeders can suppress it, making an ordinary community an unsuitable default.
Sexual dimorphism
Adult males show stronger patterning, broader heads, and more extended fins.
Notes
It has frequently been sold or photographed under the name Betta anabatoides. Gold scales, a dark line from the black lower lip through the eye toward the gill cover, and a barred tail with projecting central rays offer useful recognition clues. Check provenance rather than relying on a picture caption.
