概述
德胡氏歧须鮠（Synodontis dhonti）是坦噶尼喀湖的大型歧须鮠，天然生活在光线很弱的深水区，采集不易。幼鱼有斑点，长大后逐渐消失，不能仅凭幼鱼花纹与其他湖产歧须鮠混为一谈。
分布与栖息地
为坦噶尼喀湖特有种，生活深度至少可达约 100 m。这解释了它在缸内偏好昏暗、遮蔽充足环境的特点，深水分布本身并不等于夜行性已经得到确认。
饲养环境
可采用坦湖式石景，稳固堆石形成洞穴，同时留出开放游泳空间。降低光照有助于它露面；若光线较亮，则更需要充足石洞与遮蔽。饲养要按大型成鱼安排，不能只依据幼鱼购买时的大小。
食性与喂食
按照歧须鮠属的多样摄食习性，可用活饵、冷冻饵料与干饲料，搭配去皮豌豆、黄瓜等植物性食物。它会用下颌牙齿刮食这些食物。
习性与混养
不要与足以被吞下的小鱼混养。体形较大的硬水慈鲷是可考虑的伙伴，环境上以合适的坦湖鱼较容易匹配。它对同种有领地性，群养需要明显增加空间和躲避位置。
雌雄区分
成年雌鱼通常更丰满。雄鱼生殖乳突较长、尖而有棱，雌鱼较圆。检查有鳍棘受伤风险，不适合仅为日常分性随意抓鱼翻转。
繁殖
野外在开放水域散卵，亲鱼不护卵育幼。没有可直接照做的普通缸内育成流程，不能借用其他坦湖歧须鮠的繁殖方式。
补充说明
深水栖息、偏独居的生活方式使其不易采集。成体失去幼鱼斑点是正常变化，不宜单凭这一点怀疑发生了疾病。

Overview
A large Lake Tanganyika squeaker, Synodontis dhonti comes from dim deep water and is difficult to collect. Juveniles carry spots that disappear with maturity. Their early pattern should not be used alone to equate them with other Tanganyikan catfishes.
Distribution & habitat
It is endemic to Lake Tanganyika and inhabits depths reaching at least about 100 m. Low light in that habitat explains the value of dim conditions and cover in captivity; depth alone does not establish nocturnal behavior.
Aquarium setup
A Tanganyika-style rocky layout should contain secure caves alongside open swimming space. Reduced lighting encourages activity. Under brighter conditions, extensive rock cover becomes especially important. Plan for a large adult rather than the size of a juvenile offered for sale.
Diet & feeding
Following the varied feeding approach used for squeakers, offer live, frozen, and dry foods with plant items such as shelled peas or cucumber. The lower-jaw teeth are used to scrape these foods.
Behaviour & compatibility
Exclude companions small enough to be swallowed. Larger hardwater cichlids, especially suitable Tanganyikan species, can be considered. Conspecific territoriality means that a group requires substantially more space and retreats than housing one fish.
Sexual dimorphism
Adult females tend to be fuller-bodied. Male genital papillae are longer, pointed, and ridged, while the female structure is rounder. Examination involves handling risks from sharp spines and is not a casual routine sexing exercise.
Breeding
Wild fish scatter eggs in open water without parental care. A practical aquarium rearing procedure is not established here, and the reproductive behavior of other lake squeakers should not be transferred to this species.
Notes
Deep habitat and a largely solitary lifestyle restrict collection opportunities. Loss of juvenile spotting is an age-related change rather than, by itself, evidence of illness.
