概述
灰黄拟丽鱼（Pseudotropheus flavus）在岩栖慈鲷中不算特别凶，适合与体型、性情相近者搭配。它与长体拟丽鱼类群既可能激烈争斗又可能杂交，选伙伴时应特别避开这一类。
分布与栖息地
马拉维湖特有，目前记录集中于奇尼扬夸齐岛和奇尼扬姆韦齐礁，栖于岛礁周边岩区。
饲养环境
可从约 90 × 45 × 38 厘米开始，沙底配大量稳定岩洞，石堆间留小片活动区。岩面藻类可保留，繁殖另留平石和开阔底面。
食性与喂食
食谱应有较大比例植物成分，如含螺旋藻薄片、烫菠菜或海苔，辅以活饵和冷冻饵料。避免牛心等肉类食物。
习性与混养
既不适合大型强势岩栖类，也不适合温和孔雀类和乌塔卡类。普通缸一雄配多雌更合适，多雄需要很大空间。长体拟丽鱼及其近似类群应避免混入。
雌雄区分
雄鱼的颜色明显比雌鱼丰富。
繁殖
雌鱼口孵，可一雄至少三雌，参考水温 25～26.5 °C、酸碱度 8.2～8.5。雄鱼清理场所并展示强烈体色，雌鱼产卵收入口中后，啄雄鱼臀鳍卵点时取得精子受精。约含三至四周，期间停食；受惊可能吐卵或吞卵，若为避开追逐或捕食而移缸，应减少干扰。释放鱼苗可吃丰年虾无节幼体、微虫及粉状干粮。

Overview
Moderate by mbuna standards, Pseudotropheus flavus can fit a community of similarly sized rock cichlids. Members of the P. elongatus complex are a notable exception because serious male conflict and hybridization can both occur.
Distribution & habitat
Records are restricted to Chinyankwazi Island and Chinyamwezi Reef in Lake Malawi, where it occupies rocky habitat.
Aquarium setup
A tank around 90 by 45 by 38 cm is a starting point. Use sand, abundant cave-forming rocks, and small open gaps. Retain algae for grazing and include flat stones or open patches for spawning.
Diet & feeding
Vegetable ingredients should be prominent. Spirulina-based foods, blanched greens, or nori can be supplemented with live and frozen items. Avoid rich meats such as beef heart.
Behaviour & compatibility
Choose similarly sized mbuna, avoiding both large aggressive species and very peaceful Malawians. Several females per male distribute courtship pressure; multiple males require a large aquarium. Exclude the P. elongatus complex from breeding communities.
Sexual dimorphism
Males are much more colorful than females.
Breeding
One male with at least three females can breed around 25–26.5 °C and pH 8.2–8.5. The male prepares a site and courts with intensified color. The female collects her eggs, then receives sperm while responding to the anal-fin egg spots. She incubates for about three to four weeks without feeding. Stress may cause premature release or consumption of the brood, so any protective transfer should minimize disturbance. Released fry take small live foods and powdered prepared food.
