  "origin": "印尼加里曼丹",
  "origin_detail": "东南亚黑水河流和森林沼泽环境的人工选育红龙方向，市场重点看血统、体型、鳞框和长期发色稳定性。",
  "habitat": "自然背景偏慢流、弱酸、低硬度、遮蔽感强的水域；家庭饲养要用长缸、大水体和低惊扰环境模拟稳定巡游空间。",
  "summary": "赤血红龙属于高价值红龙品系，核心观赏点是红色覆盖、鳞片光泽、厚身比例、胸鳍展开和游姿气势。",
  "temperament": "领地意识较强，成鱼更适合单养。入缸、换灯、搬缸或混养压力都会影响食欲、呼吸和发色稳定。",
  "adult_size": "60-80 cm 常见观赏体型，长期大缸可继续增长",
  "tank_size": "建议 180 cm 以上长缸，水体越稳定越利于发色",
  "water_quality": "弱酸至中性软水，水温 27-30°C，氨氮和亚硝酸盐必须为 0",
  "diet": "以高品质昆虫、虾类、小鱼和龙鱼专用饲料组合，控制脂肪和投喂量，避免长期单一活食。",
  "compatibility": "单养优先；如混养需选择体型、速度和水层错开的鱼，并提前评估冲突和抢食。",
  "selection_guide": "选鱼先看精神、呼吸、鳞片完整、背线和游姿，再看红度。过分追求短期红度容易忽略体质和后期稳定性。",
  "risk_notes": [
    "跳缸风险高，必须加盖",
    "强光和频繁拍打鱼缸会造成应激",
    "过量喂食容易引发肥胖、拒食和水质波动"

  "care_points": [
    "稳定水温 27-30°C",
    "每周记录发色、食欲和呼吸",
    "保持成熟过滤和低硝酸盐",
    "避免频繁换饲料和强刺激灯光"
  ],
  "professional_notes": [
    "红龙发色是基因、年龄、营养、灯光和水质共同结果，不能用单一灯光短期判断价值。",
    "高价红龙更需要稳定记录，照片对比要固定光源、角度和白平衡。"
