科: Aplocheilidae
线纹单唇鳉为假鳃鳉科鱼类，温和但 delicate，建议单养，原生分布于南亚（印度至斯里兰卡）。短命策略的 annual 鳉鱼：在自然中水池会消失，因此速生速死、以卵渡旱。成体约 7.5–11 cm，单养或成对，跳缸风险真实存在，适宜水温 22–25 °C。要留后代，就收卵。
Aplocheilidae species Aplocheilus lineatus comes from India to Sri Lanka. An annual-strategy killifish: in nature its pools vanish, so it lives fast and leaves eggs behind. It swims in mid-water. Adults reach 7.5–11 cm. Singly or in pairs; jump risk is real. Soft water, live foods and a tight lid cover most of what this short-lived jewel asks. Maintain 22–25 °C at pH 6.5–7.5. Undemanding once its core needs are met.
