概述
淡红墨头鱼（Garra rufa）常以“医生鱼”销售，但市售个体可能涉及多个相近种，商品名不保证准确身份。它并非典型热带鱼，日常应按已有较低水温范围照顾，而不是按温泉或美容用途推定最适温度。
分布与栖息地
原生范围涉及东地中海及中东，从土耳其、叙利亚沿岸河流和约旦河系统，延伸到两河流域及伊朗部分内陆、沿海河系。多在急流源头和支流，也可见于低地河道与水库，部分栖地会季节性干缩。
饲养环境
适合以圆石、砂砾、沉木与耐受水草组成的溪流缸。水体应清洁富氧，维持充分循环，可争取每小时超过缸水量 10 倍；光照有助硬表面形成生物膜。只放入成熟稳定的缸，严密封顶，防止它沿玻璃攀爬逃出。
食性与喂食
不是只吃藻或皮屑的鱼。日常需要植物成分较高的下沉干粮，也应喂红虫、丰年虾、碎虾肉等动物性食物，偶尔补黄瓜、瓜果、烫菠菜或西葫芦。
习性与混养
总体较温和，可与环境要求相近的鱼同养。小缸中同种间容忍度有限，单养又可能更爱追逐相似鱼；空间充足时可养 3～4 条以上，让群体形成等级，同时观察弱鱼处境。
雌雄区分
成熟雌鱼明显更厚实，较大的雄鱼头部与吻部会形成大片追星。
繁殖
野外种群可在较长时期内连续繁殖，把卵散在砾石或岩石上，成鱼不照顾后代。市售鱼有大量养殖来源，但所涉种群、确切物种及是否使用激素并不明确，不能视为统一成熟的家庭繁殖方法。
补充说明
“医生鱼”的商业用途不能证明治疗效果，也不能替代正常的观赏鱼照护。不同地域外观会变化，鳃盖上缘蓝黑斑、尾柄斑和鳍部深色斑纹在不少种群可见，但并非全部个体完全一致。

Overview
Fish marketed as Garra rufa may represent several closely related forms rather than one securely identified species. It is not a typical tropical fish. Its listed cool-water maintenance range should guide aquarium planning instead of assumptions drawn from commercial spa use.
Distribution & habitat
The accepted range extends across eastern Mediterranean and Middle Eastern drainages, including the Jordan and Tigris–Euphrates systems and parts of Iran. Habitat use includes fast tributaries, larger river channels and reservoirs, with seasonal drying at some sites.
Aquarium setup
Use stones and wood to create grazing areas in a mature stream-style aquarium. Keep water clean and well aerated, with substantial circulation; turnover exceeding ten tank volumes per hour is suggested. Illuminate some hard surfaces for biofilm and close the top securely against climbing escapes.
Diet & feeding
A balanced menu combines plant-rich sinking food with small animal items such as bloodworms, brine shrimp or chopped shrimp. Vegetables and fruit can add occasional variety. Neither algae nor the behavior behind its commercial nickname constitutes a complete diet.
Behaviour & compatibility
Three or four or more may be appropriate in an adequately sized enclosure. A lone fish can direct aggression toward similar species, while cramped groups may quarrel among themselves. Match companions to its water and space requirements rather than relying solely on its peaceful reputation.
Sexual dimorphism
Ripe females are fuller-bodied. Large males develop extensive patches of tubercles over the head and snout.
Breeding
Wild populations scatter eggs over mineral substrates through a prolonged breeding season without parental care. Large commercial output exists under this name, but the populations involved and production methods are unclear. Farm availability therefore does not establish a single validated home protocol.
Notes
Commercial claims attached to the doctor-fish name do not establish a therapeutic effect. Appearance varies geographically; dark or bluish marks near the gill cover and tail base occur in many populations, but no single color pattern resolves every trade identification.
