概述
皮尔斯氏丽体鱼（Herichthys pearsei）几乎完全植食，体型很大却相对温和。成鱼需要约 2.4 米级别的大缸，水草通常会被吃掉；选混养伙伴时必须兼顾硬、偏碱水需求。
分布与栖息地
原产墨西哥东部与危地马拉沿岸水系，栖息河流和湖泊中植被丰富的岸边区域。偶有汽水记录，但长期耐受情况不明，不宜据此按汽水鱼安排。
饲养环境
成年雄鱼或一对约需 240 × 60 × 60 厘米。沙或砾石底配大型圆滑岩块形成遮蔽，水草不宜作为持久造景期待。大体型需要足够生物过滤能力，留出成鱼转身和活动空间。
食性与喂食
野外吃多种藻类，以及水生和陆生植物，几乎以植物为全部食物。食谱应围绕这一特点安排，而不是按大型慈鲷默认大量肉食。
习性与混养
在足够大缸里可与其他大型温和鱼混养，合适大型慈鲷也只应在非常宽敞时考虑。伙伴除了尺寸相当，还要能适应相同水硬度与酸碱度。
雌雄区分
雄鱼更大、颜色更浓，成熟时额部较高。
繁殖
双亲护幼的基面产卵鱼，卵产于雄鱼预挖的坑内。可从约 6 尾幼鱼一起养大争取自然配对，配对后须为其余鱼另作安置，繁殖环境保持宽敞、硬且偏碱。

Overview
Large but comparatively placid, Herichthys pearsei is an almost entirely plant-eating cichlid. Mature fish require an aquarium on the 2.4 m scale. Plants are likely to become food, and companions must share its preference for hard alkaline water.
Distribution & habitat
It comes from coastal drainages of eastern Mexico and Guatemala, often using vegetated margins of rivers and lakes. Occasional brackish records do not establish long-term tolerance of those conditions.
Aquarium setup
An adult male or pair needs about 240 by 60 by 60 cm. Sand or gravel with large smooth rocks provides a practical layout. Do not rely on planted decoration remaining intact. Substantial biological filtration is required.
Diet & feeding
Algae and aquatic or terrestrial plants make up nearly the whole natural diet. Feeding should reflect that herbivorous specialization.
Behaviour & compatibility
A spacious community of substantial peaceful fishes is possible. Other large cichlids require especially generous quarters, and all companions must tolerate matching hard-water conditions.
Sexual dimorphism
Males grow larger, become brighter and develop a higher forehead.
Breeding
It is a biparental substrate spawner using a pit prepared by the male. Raising a juvenile group can produce a natural pair, but the other fish then need alternative housing. A large aquarium with hard alkaline water is the suggested starting point.
