概述
河栖凹鼻鲀（Tetraodon fluviatilis）是南亚及东南亚的汽水河豚，虽常在淡水中出售，长期仍需适应汽水环境。它的体形相对修长，容易与近似绿色斑点河豚混淆，购买前应先确认身份。
分布与栖息地
分布从印度、孟加拉国、斯里兰卡延至缅甸、泰国、老挝、柬埔寨、越南及印度尼西亚，常在河流和河口的缓流水段活动。
饲养环境
可参考 120 × 30 × 30 厘米。使用砂底、石块和沉木提供遮蔽，可添加能适应轻度盐水的耐受植物，或以人工植物替代。用海盐配成约 1.005–1.010 比重的汽水，也能耐受海水条件；淡水店养状态不代表适合长期淡水。定期部分换水，避免水质恶化。
食性与喂食
贝类、蠕虫和适口活冷冻饵都可提供，定期安排带壳螺、蟹足、贻贝等，帮助磨耗不断生长的喙齿。只有柔软食物容易忽略长期齿板维护。
习性与混养
对伙伴不太宽容，常骚扰、咬鳍，慢游和长鳍鱼尤其不合适。只有大空间中才可谨慎考虑强健活跃、能共用汽水的伙伴。对同种也常发生冲突，空间不很充足时不宜多尾同缸。
繁殖
有缸内产卵记录：雌鱼将卵产在平坦表面，雄鱼守护至孵化。不能由这两点推定已有稳定的家庭育苗流程。

Overview
Often offered from freshwater tanks, Tetraodon fluviatilis is a brackish-water puffer whose long-term setup must reflect that requirement. It has a comparatively streamlined form and is easily confused with similar green-spotted relatives. Identification therefore directly affects care.
Distribution & habitat
Its range extends from India, Bangladesh, and Sri Lanka across mainland Southeast Asia to Indonesia. Slower stretches of rivers and estuaries are characteristic habitats.
Aquarium setup
A 120 by 30 by 30 cm aquarium is the suggested reference. Sand, rock, and wood provide shelter; hardy plants may persist under mildly saline conditions, while artificial plants are an alternative. The recommended specific gravity is about 1.005–1.010, and full marine conditions can also be tolerated. Regular partial changes are essential, regardless of how the fish was held in the shop.
Diet & feeding
Offer shellfish, worms, and suitable live or frozen foods. Regular shell-on snails and hard-shelled portions help keep the growing dental plates worn down; food texture matters alongside acceptance.
Behaviour & compatibility
It commonly harasses companions and nips fins, especially those of slow or long-finned fish. Only spacious systems offer reasonable scope for robust, active brackish-water companions. Conspecific belligerence also makes multiple specimens a poor choice without substantial room.
Breeding
Aquarium spawning has occurred, with eggs laid on a flat surface and guarded by the male until hatching. This observation does not by itself establish a dependable rearing procedure.
