概述
墨绿凹鼻鲀（Tetraodon nigroviridis）是活跃好奇的斑点河豚，虽常被当作混养鱼出售，实际会咬鳍，部分个体长大后更难容忍伙伴。它既有淡水也有汽水记录，安排环境和伙伴时必须同时考虑盐度、空间及攻击风险。
分布与栖息地
分布从印度、斯里兰卡经缅甸、泰国、柬埔寨、越南，延至马来西亚、印度尼西亚和菲律宾。生活环境包括沿岸汽水以及淡水河流、溪流、湖泊和洪泛区。
饲养环境
可参考 120 × 30 × 30 厘米。砂底、密植水草、根枝及浮水植物形成遮蔽，仍要留下开阔游动区；柔软叶片可能被咬。水质恶化很容易出问题，必须规律部分换水。可用淡水维持，也有用海盐调至约 1.005 比重更有利于寿命的观察。
食性与喂食
喂适口贝类、蠕虫及活冷冻饵，定期加入带壳小螺、蟹足和虾等硬质食物，帮助磨耗持续生长的喙齿。不能只依靠柔软食物长期维持。
习性与混养
慢游、长鳍鱼容易被咬，伙伴宜强健活跃且能共用盐度，但仍须观察个体差异。同种常有冲突，雄鱼尤其可能持续打斗；没有很大空间不宜多尾。坚持群养时，四尾以上配丰富躲藏处和视线遮挡只能分散攻击，不能消除风险。
繁殖
有人工产卵记录，但繁殖需汽水。提供平坦石面，卵可直接产在底部或石面，由雄鱼守护，约七天孵化后再被移入底床小坑，继续受保护。鱼苗据报道很难养，许多饵料不适用，剑水蚤无节幼体有部分成功经验。
补充说明
与其他斑点河豚容易混淆，较圆的体形和腹部缺少明显棘刺可作辅助线索，仍需结合整体外形判断。

Overview
Active and inquisitive, Tetraodon nigroviridis is often sold for communities despite fin biting and sometimes increasing aggression with age. It occurs in fresh and brackish habitats. Salinity, space, and temperament must all be considered when planning its aquarium.
Distribution & habitat
Its range extends from India and Sri Lanka across mainland Southeast Asia to Malaysia, Indonesia, and the Philippines. Habitats include coastal brackish water and freshwater rivers, streams, lakes, and flooded areas.
Aquarium setup
The suggested reference dimensions are 120 by 30 by 30 cm. Combine sand, dense plants, wood, and floating shade with open swimming areas; tender foliage may be chewed. Regular partial changes are essential. Freshwater maintenance is possible, while marine salt giving about 1.005 specific gravity has been associated with better longevity.
Diet & feeding
Offer suitable shellfish, worms, and live or frozen foods, regularly including shell-on snails and other hard-shelled portions. These help wear the continuously growing dental plates, something an exclusively soft diet cannot provide.
Behaviour & compatibility
Slow or long-finned fish are vulnerable. Robust, active companions sharing the water conditions are more plausible, but individual responses vary. Conspecific conflict, particularly repeated male fighting, makes multiple fish unsuitable without substantial space. Four or more with visual barriers may distribute aggression; it does not remove it.
Breeding
Aquarium spawning has occurred in brackish water. Flat stones provide potential sites, with eggs placed on rock or substrate and guarded by the male. After roughly seven days, hatchlings are moved into a prepared bottom pit and remain guarded. Rearing is reportedly difficult; Cyclops nauplii have brought some success where other foods failed.
Notes
A rounded body and lack of conspicuous belly spines contribute to identification among similar spotted puffers. Use several characters together rather than a trade label alone.
