概述
里根氏丽体鱼（Maskaheros regani）是墨西哥的大型慈鲷，饲养难点往往在于让个体彼此安全共处。相容配对可能长期相安，也可能出现雄鱼欺压雌鱼，最后不得不单独安置的情况并不少见。
分布与栖息地
本种为墨西哥 Coatzacoalcos 河流域特有鱼，生活在岩石较多的河流环境。
饲养环境
成年配对可参考至少约 120 × 60 厘米的底面积，并为分隔个体预留方案。沙或细砾均可，岩石、沉木及枝条必须稳固；它会自行调整装饰，松动重物可能威胁缸体。灯光没有特殊要求，过滤应有足够处理能力。
食性与喂食
野外主要摄取藻类、碎屑及附着生物群，整体偏草食。可用优质慈鲷颗粒补充，再适量搭配虾、贝肉和白肉鱼等，不能因愿意吃动物性饵料就把它按纯肉食鱼喂养。
习性与混养
属于中等攻击性的慈鲷。足够大的缸内，可尝试与强健中美洲慈鲷组合，用岩石及沉木划分各自区域，但没有保证成功的组合。即使一对已经建立关系，也要持续观察雌鱼是否遭到欺压。
雌雄区分
雄鱼较大、更鲜艳，会形成额隆，背鳍和臀鳍也较延长。
繁殖
安全配对是主要障碍；一旦能够稳定共处，产卵通常不难。双亲会清理大石面或洞内产卵位置，移开碎屑。雄鱼在产卵时可能攻击雌鱼，若程度过重应把雌鱼隔离。
卵约 2～3 天孵化，再约四天仔鱼自由游动。先喂刚孵化丰年虾，随后过渡到微虫、仔鱼饵及压碎干粮。双亲通常护幼良好，但准备下一次产卵时可能开始攻击这一窝幼鱼，应及时分开。
补充说明
市场可能仍使用旧名 Vieja regani 或 Cichlasoma regani。这些历史名称应与现用学名对照，避免因不同属名误以为一定是不同鱼。

Overview
Maskaheros regani is a large Mexican cichlid whose main challenge is often safe coexistence. Compatible partners may settle well together, but female bullying remains possible and individual housing is sometimes the practical outcome.
Distribution & habitat
It is endemic to Mexico's Coatzacoalcos basin, where rocky rivers provide its natural habitat.
Aquarium setup
For adults kept as a pair, a footprint of at least approximately 120 × 60 cm is a reference, with a means of separating fish available. Sand or fine gravel can be used. Secure rocks, wood and branches carefully because the fish rearranges furnishings and dislodged heavy objects may damage the aquarium. Lighting is flexible, while adequate filtration is necessary.
Diet & feeding
Natural feeding is primarily herbivorous, involving algae, detritus and attached growth. Quality cichlid pellets can supplement this, with some prawn, mussel or white fish. Acceptance of animal foods should not turn the feeding plan into an exclusively meaty diet.
Behaviour & compatibility
This is a moderately aggressive cichlid. Robust Central American companions may be attempted in sufficient space, using rocks and wood to divide territories, but success is not assured. Continue to watch the female even in an established pair.
Sexual dimorphism
Males are larger and more colorful, developing a forehead hump and extended dorsal and anal fins.
Breeding
Forming a pair that can live together is the principal difficulty; spawning is usually straightforward afterward. The adults clear debris from a large stone or cave surface. Male attacks can occur during spawning, and excessive violence requires protection and separation of the female.
Eggs hatch in approximately two to three days, followed by free swimming about four days later. Begin with newly hatched brine shrimp, then progress to microworms, fry foods and crushed dry preparations. Both parents generally care well for offspring, but may attack the existing brood when ready to spawn again. Remove the young at that stage.
Notes
The older names Vieja regani and Cichlasoma regani may still appear in trade. Match these historical combinations to the current name rather than assuming each genus label denotes a different fish.
