概述
多带后鳍花鳅（Kichulchoia multifasciata）来自高氧急流，皱褶唇面、较短须和体侧暗带可辅助辨认。它需要成熟表面上的藻膜作为长期食源，刚入新环境时还可能跳缸。
分布与栖息地
已知来自韩国西南部河流，主要限于浅、快流、高氧的源头溪流与小支流。浅滩和流动河段可与水潭、跌水交替，底部多沙砾与岩块，日照配合清水使附着生物丰富。
饲养环境
至少参考 90 × 30 厘米底面积，大容量过滤可按每小时十至十五倍循环量参考，并增氧。沙砾、圆石及根木提供结构，耐流水草也可用。缸体须成熟，除观赏玻璃外可保留附着藻膜；定期换水、盖好缸以防跳跃。
食性与喂食
可能主要利用底栖藻及附着微生物，缸内虽接受干粮和红虫等，却不宜过量蛋白。可用蔬菜、螺旋藻比例高的凝胶食物，仍应持续提供长藻石等成熟表面。主缸不足时，可另缸强光培养藻石并轮换。
习性与混养
性情温和，但伙伴必须匹配溪流环境。耐流小鱼、部分虾虎及温和鳅类可考虑，先排除好斗或强竞争者。可按同科群体偏好建议四至五尾以上同养。
雌雄区分
雄鱼缺少某些鳅类胸鳍圆盘，幼鱼较难分性。老龄雌鱼更大，体躯似更深厚。
补充说明
体侧条纹可断裂或个体间变化，尾鳍基部还有一条暗带。眼下棘能受惊竖起，捞取防止挂网。

Overview
Wrinkled lips, short barbels, and dark body bars help identify Kichulchoia multifasciata. Long-term care requires a mature high-oxygen system with productive grazing surfaces. Newly introduced fish may jump, making a secure cover important.
Distribution & habitat
Known from southwestern Korean drainages, it occupies shallow oxygen-rich headwaters and small tributaries. Riffles and runs can alternate with pools or cascades over sand, gravel, and rocks. Clear water and sunlight support abundant surface growth.
Aquarium setup
Use at least a 90 by 30 cm footprint with substantial filtration and aeration. A turnover around ten to fifteen tank volumes per hour is suggested. Gravel or sand, rounded stones, and wood provide structure; hardy plants are optional. Preserve growth on grazing surfaces while maintaining regular water changes, and fit a secure cover.
Diet & feeding
The natural diet probably includes substantial benthic algae and associated microorganisms. Accepted prepared or animal foods should not produce an excessively protein-rich diet. Vegetable- and spirulina-rich gel foods can supplement, while established algae-coated surfaces remain central. Rocks can be grown separately under bright light and rotated through the aquarium.
Behaviour & compatibility
Peaceful behavior permits compatible stream fishes, selected gobies, and nonaggressive loaches. Check for excessive competition before mixing. A group of at least four to five follows the suggested social arrangement.
Sexual dimorphism
Males lack a pectoral lamina, making juveniles difficult to sex. Older females grow larger and apparently deeper-bodied.
Notes
Body bars can vary or break into segments, with an additional band at the tail base. Subocular spines can catch in netting when erected under stress.
