概述
美尾里根氏丽鱼（Reganochromis calliurus）是深水生活的坦噶尼喀湖慈鲷，采集不易，因此水族贸易中少见。它性情较温和，形成配对后却会守域，繁殖由双亲共同口孵。
分布与栖息地
坦噶尼喀湖特有，常在沿岸约 60 米或更深水域活动，底部多为沙或泥。
饲养环境
可参考约 120 × 45 × 38 厘米，以沙底和较简洁布景为主，后方放一些岩石提供安全感及繁殖洞穴。
食性与喂食
活饵与冷冻食物宜作主要食物，天然食谱不以植物为组成部分。投喂可围绕合适的水生饵料安排。
习性与混养
宜成对饲养，不与强势岩栖慈鲷或食谱需求明显不同的鱼搭配。若保留多对，应提供很大的空间，因为配对后会驱赶同种。
雌雄区分
没有明显可靠的外部雌雄差异，可通过自然配对观察进一步判断；专业生殖孔检查才可能更确定。
繁殖
繁殖有一定难度。可从至少六至八尾幼鱼自然配对，参考酸碱度 8～9、水温 24～25.5 °C。配对鱼常一起入洞并开始守域；在洞中产卵后双亲轮换口孵，窝大时也可能各含一部分。约三周放出平游鱼苗，可喂丰年虾无节幼体或微虫。

Overview
Deep-water habits make Reganochromis calliurus difficult to collect and uncommon in aquaria. Generally peaceful, it becomes territorial after pairing. Both parents participate in mouthbrooding.
Distribution & habitat
It is endemic to Lake Tanganyika and usually occurs around coastal areas at depths of about 60 m or more, over sand or mud.
Aquarium setup
A tank around 120 by 45 by 38 cm can use a relatively open sandy layout. Place some rocks toward the back to offer shelter and breeding caves.
Diet & feeding
Live and frozen foods should provide the main meals. Plant material is absent from the described natural diet, so suitable aquatic animal foods are the focus.
Behaviour & compatibility
Maintain pairs with calm companions that have compatible dietary needs. Avoid boisterous mbuna. Several pairs require a large aquarium because established partners defend space against conspecifics.
Sexual dimorphism
Obvious external sex differences are lacking. Natural pair formation can guide observation, while reliable vent examination requires experience.
Breeding
Begin with six to eight or more juveniles and allow pairs to form naturally. Around pH 8–9 and 24–25.5 °C is suggested. Partners spend time together in a cave and begin territorial defense. After cave spawning, they exchange the brood or may each carry part of a large brood. Free-swimming young are released after approximately three weeks and accept brine shrimp nauplii or microworms.
