概述
Kryptopterus geminus 是会群游、性情较胆怯的鲶鱼，与一种外形极近的鱼长期混淆。它需要较大游动空间和成熟稳定的水体，不能只凭“玻璃猫类”贸易标签判断尺寸和混养需求。
分布与栖息地
已知来自泰国、老挝、柬埔寨和越南的湄公河中下游，上溯至少到老挝万象；泰国湄南河下游也有记录。栖息于有流动的河流和较大溪流，水常因悬浮泥沙而浑浊。
饲养环境
布景形式不苛刻，但宜弱光并提供遮蔽，空旷无遮蔽时容易受惊。只放入已经成熟稳定的缸，避免开缸早期水化学波动带来的压力。
食性与喂食
天然可能捕食甲壳类、其他无脊椎动物和较小鱼；人工无需依赖这些活猎物。可轮换沉底干粮、活或冷冻红虫、水蚯蚓，偶尔给小蚯蚓。
习性与混养
通常平和，但可能捕食小鱼。较大、强势或过于吵闹的伙伴容易压制它，优先考虑体形相仿、温和的鲤科鱼、鳅和其他鲶鱼。建议至少四尾同种一起饲养，以满足其群居群游习性。
繁殖
水族箱繁殖尚无记录。野外在雨季开始时产卵，幼鱼常见于季节性淹水区域。
补充说明
它可能仍以近似种名称出售。较窄的头部、较长的吻和臀鳍，以及位置更偏侧面的眼睛，是与曾混淆类型比较时的识别线索。

Overview
A schooling but timid catfish, Kryptopterus geminus has long been confused with a very similar relative. It needs substantial swimming room and a mature, stable aquarium. Broad glass-catfish trade labels are insufficient guides to its size or compatibility.
Distribution & habitat
Records extend through the middle and lower Mekong in Thailand, Laos, Cambodia, and Vietnam, at least upstream to Vientiane, and into Thailand’s lower Chao Phraya. Flowing rivers and larger streams often carry substantial suspended sediment.
Aquarium setup
Decor is flexible, but subdued light and refuge help prevent skittishness. Stock only an established system, since instability in water chemistry can cause problems during an aquarium’s immature stage.
Diet & feeding
It probably takes crustaceans, other invertebrates, and smaller fishes in nature. Live prey is not required in captivity. Rotate sinking dry preparations with live or frozen bloodworms and Tubifex, adding an occasional small earthworm.
Behaviour & compatibility
Usually peaceful, it may still prey on small fish. Much larger, forceful, or boisterous neighbors can outcompete it. Comparable peaceful cyprinids, loaches, and catfish are better candidates. Keep at least four of its own kind to accommodate its schooling tendency.
Breeding
Aquarium reproduction is unrecorded. Wild spawning occurs as the wet season starts, and juveniles are common in seasonally flooded ground.
Notes
Trade specimens may still carry the name of a similar species. A narrower head, longer snout and anal fin, and more laterally positioned eyes provide comparative identification clues.
