概述
格雷歧须鮠（Synodontis greshoffi）是一种不常进口的斑纹鲶鱼，成鱼体形不适合普通小型综合缸。它随成熟会出现轻度领地行为，尤其面对其他歧须鮠，但在空间足够、各有藏身处时仍有小群共养的可能。
分布与栖息地
分布于刚果民主共和国和喀麦隆，在刚果民主共和国中部不同地区、不同生境中出现。
饲养环境
使用柔软底床，石块、沉木和树根形成多个隐蔽角落。照明偏暗，浮水植物能柔化光线，其他水草有益但并非必需。养多尾时，把藏身点分散布置比只设置一处大洞穴更合适。
食性与喂食
可按歧须鮠属多样的人工菜单，提供活饵、冷冻饵料与干饲料，另加去皮豌豆、黄瓜等植物性食物。它会用下颌牙齿刮食这些食物，不能只从吃蔬菜或接受干饲料推定完整野外食性。
习性与混养
不要与足够小、可能被吞下的鱼混养。合适体形的非洲脂鲤、结实慈鲷、象鼻鱼、刀鱼、丝足鱼及较大鲃类可以考虑。成年后对同属鱼的领地反应更明显，但通常不如一些同属强势种激烈。小群共养要求空间充足，每尾都有可退回的遮蔽处。
雌雄区分
成年雌鱼通常更丰满。雄鱼生殖乳突较尖长、有棱，雌鱼较圆；检查涉及抓取带尖鳍棘的鱼，需有经验者操作。
繁殖
野外会在季节性淹水、微生物丰富的区域散卵，亲鱼不护卵育幼。自然过程的描述不能直接当作缸内稳定繁殖方案。
补充说明
本种与某些斑纹近似的歧须鮠容易混淆，不能仅凭体色或不常见的贸易标签确定身份。

Overview
Infrequently imported Synodontis greshoffi becomes too substantial for an ordinary small community. Mild territoriality develops with maturity, particularly toward other squeakers, but small groups can be possible when space and individual shelters are adequate.
Distribution & habitat
Its range includes the Democratic Republic of Congo and Cameroon. Records from central parts of the former cover several habitat types rather than one narrowly defined setting.
Aquarium setup
Use soft substrate with multiple shaded retreats formed by stones, wood, and roots. Subdued illumination and floating vegetation help soften the light. Other planting is beneficial but optional. For several fish, distribute shelters around the aquarium rather than creating a single favored cave.
Diet & feeding
Follow the varied captive menu recommended for squeakers: live, frozen, and dry foods plus plant items such as shelled peas and cucumber. These can be scraped with the lower-jaw teeth. Acceptance of vegetables or dry foods does not by itself define the entire natural diet.
Behaviour & compatibility
Exclude fishes small enough to be swallowed. Suitably sized African tetras, robust cichlids, mormyrids, knifefishes, gouramis, and larger barbs can be assessed as companions. Territorial behavior becomes more evident with age, especially toward related catfishes, though it is generally less intense than in some aggressive relatives. A small group needs substantial room and a refuge for every fish.
Sexual dimorphism
Adult females tend to be fuller-bodied. Male genital papillae are longer, pointed, and ridged, whereas female structures are rounder. Examination calls for experience because the fish has sharp fin spines.
Breeding
Wild fish scatter eggs in seasonally flooded areas rich in microorganisms and provide no parental care. This describes natural reproduction rather than an established routine aquarium method.
Notes
Similar patterning in other squeakers can cause confusion. Color or an unusual sales label alone is not sufficient for identifying this species.
