概述
Tetraodon suvattii 是典型伏击型河鲀，多数时间埋在底砂里等猎物。眼睛靠头顶、嘴向上，有利于从下方突袭；它会吃能入口的鱼，也会咬伤更大的伙伴，通常应单养。
分布与栖息地
来自泰国和老挝的河流主道，多见于泥底，也可生活在岩石底部。
饲养环境
这是淡水鱼，无需为日常饲养加盐。铺足够深的细砂让鱼埋身，再用光滑石块和沉木遮蔽，也可种水草。单尾可参考 75 cm、约 70 L 的鱼缸；活动量不高仍需认真维持水质，规律部分换水。
食性与喂食
需要肉食，可用虾、蚯蚓、适口鱼肉和贝肉。部分新鱼起初只吃活饵，但多数能转吃非活饵。它活动少，不必天天投喂；幼鱼可隔天一餐，成鱼每周一至两餐即可。
习性与混养
不适合一般混养：小鱼会被吞，大鱼也可能被咬掉组织。同种之间同样不宽容，只有在很大的缸内提供大量藏身处及视觉隔断时才可考虑多尾，零星混养成功不能当作安全保证。
底砂不适合埋身时，它可能拟态成覆藻石块；体色也会随状态和环境改变。
雌雄区分
无法凭可靠的外部特征分辨雌雄。
繁殖
已有玩家繁殖记录。亲鱼在底床挖小坑产卵，也可能直接产在平石上；求偶时双方似乎会鼓起身体展示。受精后由雌鱼守卵至孵化，鱼苗消耗完卵黄后可吃丰年虾无节幼体。

Overview
An ambush specialist, Tetraodon suvattii spends most of its time buried and waiting. High-set eyes and an upward-facing mouth aid attacks from below. It swallows small fishes and bites pieces from larger ones, so solitary care is the usual choice.
Distribution & habitat
It inhabits main river channels in Thailand and Laos, occurring over rock but more commonly mud.
Aquarium setup
No salt addition is needed for this freshwater puffer. Supply a sand layer deep enough for burial, with smooth rocks, wood, and optional plants for cover. A 75 cm aquarium of about 70 L is a reference for one fish. Low activity does not reduce the need for clean water and regular partial changes.
Diet & feeding
Offer a meaty diet of shrimp, earthworms, suitable fish pieces, and mussel. Some individuals initially demand live food, but most can adapt to nonliving alternatives. Because activity is low, juveniles can be fed every other day and adults only once or twice weekly.
Behaviour & compatibility
Ordinary community housing is unsafe: small fish are prey, and larger fish can still be bitten. Conspecifics are also poorly tolerated. Multiple individuals are an option only in a large, heavily divided aquarium; isolated reports of compatible tankmates do not guarantee safety.
When unable to bury, it may resemble an algae-covered rock. Color can change with its surroundings or state.
Sexual dimorphism
Reliable external sex differences are unavailable.
Breeding
Aquarium breeding has occurred. Eggs are laid in an excavated depression or directly on a flat rock. Courtship apparently includes both fish inflating during displays. The female guards fertilized eggs until hatching, and the young accept Artemia nauplii after absorbing their yolk.
