概述
屈氏突吻丽鱼（Labeotropheus trewavasae）具有突出吻部和刮藻牙齿，体形比相近的菲氏突吻丽鱼更纤细、体型更小。它对同种很强势，选择它应同时考虑群体组成与躲避空间。
分布与栖息地
马拉维湖特有，广布于多处沿岸及岛屿，包括马莱里等岛群。常见于藻类丰富的岩区，上层水域波动大、含氧高，也记录于约 34 米深处。
饲养环境
基本布置可参考约 90 × 45 × 38 厘米的缸，繁殖群宜提供约 120 厘米长度。用沙底和稳固石堆形成洞穴，石堆之间留少量开阔区并充分充氧。水草会被啃食，不宜依赖水草提供遮蔽。
食性与喂食
含螺旋藻薄片、烫菠菜等植物食物应占较大比例，再用活饵和冷冻食物补充变化。
习性与混养
攻击性与领地性明显，不适合温和孔雀类或乌塔卡类慈鲷。可谨慎与其他强健岩栖慈鲷搭配，同种雄鱼之间尤其容易冲突；一雄配多雌有助于分散求偶压力。群养仍须观察被持续追逐的个体，不可把提高密度视为自动消除攻击的方法。
雌雄区分
雄鱼臀鳍卵点较清晰，雌鱼通常淡得多或缺失。体色地域差异很大，部分雄鱼还可能呈雌鱼式花色。
繁殖
通常为雌鱼口孵，可一雄配至少三雌，在平石和沙地上求偶。繁殖参考酸碱度 8.2～8.5、水温 25～26.5 °C；雄鱼守住场所并积极追雌。雌鱼捡起卵，再啄雄鱼臀鳍卵点，受精发生于这一互动中。每窝约 10～40 粒，口孵可持续 3～4 周，雌鱼期间停食。受惊可能提前吐卵或吞卵，长期离群又影响回群地位，移动含卵雌鱼需谨慎。鱼苗游出后可吃丰年虾无节幼体。
补充说明
野生花色记录超过 40 种，尤其背鳍差异很大；不同地域型和同属近缘种应分开繁殖。另有少数地区雄鱼含卵的记录，因此通常雌性口孵不等于绝无例外。

Overview
Compared with Labeotropheus fuelleborni, L. trewavasae has a slimmer body and a smaller adult size. Its projecting snout and specialized teeth suit rock grazing. Strong aggression toward conspecifics makes group composition a central part of aquarium planning.
Distribution & habitat
This Lake Malawi endemic is widespread along shores and around island groups, including the Maleri islands. It occupies algae-covered rock habitat, from turbulent, oxygen-rich shallows to recorded depths of roughly 34 m.
Aquarium setup
Start with a tank around 90 by 45 by 38 cm, using a longer aquarium of roughly 120 cm for a breeding group. Sand, secure cave-forming rocks, open gaps, and ample oxygen are appropriate. Plants are likely to be eaten.
Diet & feeding
Vegetable matter should make up a substantial share of meals. Spirulina-based foods and blanched greens can be supplemented with live and frozen foods.
Behaviour & compatibility
Avoid peaceful peacocks and utaka. Other robust mbuna may be considered, but conspecific aggression can be severe. Several females per male can distribute courtship pressure. A busy community still requires close observation; crowding alone does not guarantee tolerable aggression.
Sexual dimorphism
Male anal-fin egg spots are usually distinct, whereas those of females are faint or absent. Local variation is extensive, and some males show female-like coloration.
Breeding
A breeding group can comprise one male and at least three females, with flat rocks and open sand. Suggested conditions are pH 8.2–8.5 and 25–26.5 °C. The male courts forcefully. The female gathers the eggs and receives sperm while responding to his anal-fin egg spots. She normally carries 10–40 eggs for up to three or four weeks without eating. Disturbance can lead to premature release or brood loss, and extended isolation can upset her position in the group. Released fry accept brine shrimp nauplii.
Notes
More than 40 wild color forms have been recorded, with particularly variable dorsal fins. Keep local forms and related species separate to prevent hybridization. Unusual records include males carrying eggs in some populations; maternal incubation describes the usual pattern.
