概述
丘疹鲀（Tetraodon pustulatus）原生于克罗斯河流域，活跃而好奇，需要大型且环境丰富的缸。它主要捕食软体动物，混养可能性比某些大型河豚高，但相近体形的鱼仍可能遭到试探性啃咬。
分布与栖息地
为尼日利亚和喀麦隆的克罗斯河流域特有种，水族贸易个体多从喀麦隆采集后经尼日利亚出口。生活在水流较快的主河道，石区或有落木的地段均可见，偶尔也进入河口条件。
饲养环境
150 × 60 × 60 厘米只是最低起点，长期宜更宽裕。用沉木、石块和植物提供探索空间，同时保留充分游动区；通常不明显破坏水草。它进食残渣多，需要较大的外置过滤或底滤，密切关注水质。以近中性的淡水为目标，虽然短期能耐受低盐，也不必因此长期加盐。
食性与喂食
天然以软体动物为主，也摄入甲壳类、其他无脊椎动物，有时吃鱼。饵料要多样，可用适口螺、蟹、虾、昆虫和蚯蚓等，规律提供带壳食物磨耗喙齿。部分从幼鱼训练可接受优质颗粒，但不能取代硬壳饵。避免长期单一海鲜贝肉、哺乳动物肉和禽肉，也不宜用活饵鱼作日常食物。
习性与混养
较小、温和且游得快的伙伴通常较少被理会，体形接近的大鱼反而可能被咬。混养应持续观察，天然偶尔吃鱼的事实意味着不能把任何小鱼组合视为绝对安全。
雌雄区分
没有已确认、明显的外部雌雄差异。
补充说明
原生流域存在栖地退化和污染压力，贸易中较少见。

Overview
An active, inquisitive Cross River puffer, Tetraodon pustulatus requires a large, varied aquarium. Its natural feeding centers on mollusks and other relatively slow prey. Some community combinations are possible, but exploratory biting remains a concern, especially with similarly sized fish.
Distribution & habitat
It is endemic to the Cross River basin of Nigeria and Cameroon. Aquarium specimens are mainly collected in Cameroon and exported through Nigeria. Moderately fast main channels contain varied rocky or woody areas, and occasional records come from estuarine conditions.
Aquarium setup
Treat 150 by 60 by 60 cm as a bare minimum and allow more room for long-term care. Wood, rocks, and plants provide interest without blocking swimming space. Plants are seldom damaged. Messy feeding demands a substantial external filter or sump and close water-quality monitoring. Aim for near-neutral freshwater; temporary low-salinity tolerance does not establish a need for permanent salt.
Diet & feeding
Natural prey include mollusks, crustaceans, other invertebrates, and occasional fish. Vary appropriate snails, crabs, prawns, insects, and earthworms. Some fish can learn to take pellets from youth, but regular hard-shelled foods remain essential. Avoid dependence on one seafood item, mammalian or avian meats, and feeder fish.
Behaviour & compatibility
Much smaller, peaceful, fast fish are often ignored, whereas similarly sized companions may attract bites. Continued observation is necessary: occasional natural fish predation means smaller companions cannot be guaranteed safe.
Sexual dimorphism
No clear external sex differences have been established.
Notes
Habitat degradation and pollution affect the native basin, and the species is uncommon in aquarium trade.
