概述
阿拉伯鲀（Tetraodon lineatus）是大型纯淡水河豚，能与饲养者形成互动，但对其他鱼的攻击性很强。它不需要在水中加盐，通常应单养；体形和喙齿决定了误配伙伴的后果可能很严重。
分布与栖息地
分布于非洲北部、西部及部分东部地区，从尼罗河沿线到塞内加尔、尼日利亚、喀麦隆等地的湖泊和河流。既见于开阔水面，也利用水草浓密的隐蔽区域。
饲养环境
单尾空间可参考 120 × 60 × 60 厘米，但要保留充分开阔游动区。砂底配光滑石块和沉木即可；可种水草，不过叶上若有食物，取食时可能留下咬痕。不要因想混养而只略增缸体，群养所需尺度远大于单尾。
食性与喂食
天然以软体动物为食，人工可用各类适口贝类、蠕虫及活冷冻饵。带壳小螺、蟹足、贻贝等需要规律安排，以磨耗持续生长的喙齿，避免齿板过长造成摄食困难。
习性与混养
对异种和同种都强烈不宽容，能咬掉肉块甚至造成致命伤。极大缸中也仍可能互咬和打斗，所谓群养成功不能等同于和平相处；单养最符合这种风险。
雌雄区分
平时没有可靠外部性别差异。雌鱼抱卵时明显圆腹，临产前可见较小的产卵管。
繁殖
约一岁性成熟，有大型缸内繁殖记录，但攻击性使配对困难。雌鱼显出产卵管后可与愿意交配的雄鱼短暂配对，雄鱼翻身贴住雌鱼腹部，反复短促释放卵和精子，卵会下沉，总数可达数千。产后可分离亲鱼或卵。
通常约 72–96 小时孵化，鱼苗先躺在缸底或附着缸壁；降低水位，使它们较易接近水面。约一周后自由游动，先供草履虫等微小食物，避免开口期饥饿损耗，再逐渐转丰年虾无节幼体。幼鱼很早就可能攻击同伴，需按相近大小分组。

Overview
A large freshwater puffer, Tetraodon lineatus can become interactive with its keeper while remaining highly dangerous to other fish. Salt is unnecessary. Solitary housing is the standard approach because its strong beak and intolerant behavior make companion mistakes costly.
Distribution & habitat
Its broad African range includes Nile-region countries and western areas such as Senegal, Nigeria, and Cameroon. Lakes and rivers provide both open water and sheltered, densely vegetated sections.
Aquarium setup
For one fish, the suggested reference is 120 by 60 by 60 cm with substantial open swimming space. Sand, smooth rocks, and wood offer a simple layout. Plants are possible, though bites may appear when the fish takes food from leaves. Group housing requires vastly more space than a small enlargement of a single-fish setup.
Diet & feeding
It naturally specializes on mollusks. Aquarium foods can include suitable shellfish, worms, and live or frozen prey, with regular hard-shelled portions to maintain dental wear. Continual plate growth makes this a routine care requirement.
Behaviour & compatibility
Aggression extends to both unrelated fish and conspecifics. Bites can remove flesh and cause fatal injury. Even very large systems do not prevent fighting, so survival in a group should not be mistaken for peaceful compatibility.
Sexual dimorphism
Routine external sexing is unreliable. Ripe females become noticeably rounded, and a small ovipositor appears shortly before spawning.
Breeding
Breeding has been reported in large aquariums, with maturity around one year, but aggression complicates pairing. The bond lasts only through spawning. A male turns beneath a receptive female, and successive brief bouts release sinking eggs and sperm, potentially totaling several thousand eggs. Separate eggs or adults afterward.
Hatching usually takes 72–96 hours. Young initially rest on the bottom or sides, and lowering the water helps them reach the surface. Free swimming begins after roughly a week, when tiny foods such as infusoria are essential; starvation losses can be heavy. Progress to Artemia nauplii as the fry grow. Early aggression makes sorting youngsters into similar-sized groups important.
