概述
矮丽鱼（Nannacara anomala）强健且较容易繁殖，平时温和，但雌鱼守幼时会变得非常强势。它适合学习慈鲷育幼行为，前提是为繁殖后的领域变化留出空间，而不是只看日常性情。
分布与栖息地
自然分布从圭亚那阿鲁卡河延伸至苏里南马罗韦讷河下游，常见于沿海低地被水淹没的草地。市场个体多数来自亚洲或东欧的商业繁殖。
饲养环境
布置丰富水草，并用沉木和木根提供遮蔽及潜在产卵位置。若饲养多条雌鱼，每条都需要自己的底部小领域，不能把单对所需空间直接用于一雄多雌。
食性与喂食
自然捕食蠕虫、昆虫及其他小型无脊椎动物。通常能接受肉食型慈鲷颗粒作为主食，搭配红虫、丰年虾等活饵或冷冻饵料，再补充蔬菜或螺旋藻配方、少量黄瓜等植物材料。
习性与混养
平时可与多数温和小鱼共养，繁殖后则必须注意雌鱼对伙伴的驱赶。多雄在狭小环境中容易形成强烈优势关系，弱势雄鱼甚至会表现出雌鱼般的体色与体形。
雌雄区分
雄鱼明显较大，通常带浅蓝与红色；雌鱼较小，偏黄，体侧有黑色纵纹。繁殖状态的雌鱼会出现类似棋盘的斑纹。受压雄鱼可能伪装成雌鱼外观，因此仅凭某一时刻的颜色并不可靠。
繁殖
一雄一雌在合适环境中通常容易繁殖，更大的缸可安排多雌。每条雌鱼约需四十厘米见方的底部领域。护幼雌鱼能以身体动作影响幼鱼活动，同时会猛烈驱逐靠近者；混养缸发生繁殖后要重新评估空间与伙伴关系。
补充说明
若优势雄鱼消失，原来外观像雌鱼的弱势雄鱼可能在数周内恢复典型雄鱼体形、颜色和行为。这是社会压制相关的外观变化，不应直接描述为已证实的雌雄性别转换。

Overview
Hardiness and ready breeding make Nannacara anomala an accessible small cichlid. Its peaceful everyday behavior changes sharply when a female guards fry. Space for that transition is essential in any community plan.
Distribution & habitat
The native range extends from Guyana's Aruka River to the lower Marowijne in Suriname. Flooded grassland in coastal lowlands is a typical habitat. Most aquarium stock is commercially bred in Asia or eastern Europe.
Aquarium setup
Provide generous planting and wood cover, including possible spawning locations. Each female in a multi-female arrangement needs her own bottom area; space adequate for one pair is not automatically enough for a larger group.
Diet & feeding
Wild fish take worms, insects, and other small invertebrates. Meaty cichlid pellets can form a captive staple, with live or frozen bloodworms and Artemia plus some vegetable or spirulina foods and small pieces of cucumber.
Behaviour & compatibility
Most peaceful fishes can be suitable companions outside breeding. A guarding female may become extremely aggressive toward them. In restricted multi-male housing, subordinate males can adopt a female-like appearance under social pressure.
Sexual dimorphism
Males are much larger and usually show pale blue and red tones. Females are smaller and yellowish with a dark lateral stripe, developing a checkerboard pattern in breeding condition. Female-like subordinate males make a single color observation unreliable for sexing.
Breeding
A male and female generally breed readily under suitable conditions. Larger aquaria can accommodate several females, each requiring roughly a forty-centimeter-square bottom area. A caring female uses body movements with her fry while strongly repelling approaching fishes. Reassess community space and relationships when brood defense begins.
Notes
After a dominant male is removed, a suppressed male may develop typical male size, color, and behavior within weeks. This socially associated change in appearance should not be presented as proof of sex reversal.
