概述
贼弦尾鱼（Crenicara latruncularium）平时较温和，可以进入适当的小型鱼混养环境，但繁殖时雌鱼会积极守洞，甚至驱赶雄鱼。它的混养表现应按平时和育幼阶段分别观察。
分布与栖息地
原生于巴西西部的瓜波雷河及玻利维亚的马莫雷河流域。
饲养环境
布置丰富水草，并用沉木、岩石和浮水植物提供充足遮蔽。繁殖时需要可利用的洞穴，以及让被驱赶个体离开守卫区域的空间。
食性与喂食
日常可用优质慈鲷颗粒或薄片，再搭配活饵和冷冻饵料。食谱中加入藻片、螺旋藻薄片等植物成分，避免长期只喂一种食物。
习性与混养
在未繁殖时通常能与温和小型脂鲤、波鱼及小型鲶类相处。鱼对开始繁殖后，雌鱼的防卫明显增强，不能把此前和平相处当作后续安全保证。
雌雄区分
雄鱼较大、颜色更鲜明，鳃部附近的蓝色纹路较突出，背鳍与臀鳍也更长。
繁殖
在洞穴中产卵，由雌鱼守卫并驱逐靠近者，包括雄鱼。卵约三天孵化，再过四五天鱼苗开始自由游动。若雄鱼此时仍被雌鱼攻击，应将雄鱼移走。鱼苗可从丰年虾无节幼体开始，随长大逐渐转为适口的成鱼食物。
补充说明
繁殖期雌鱼主动驱赶雄鱼是管理鱼对时的重点，不能把“双亲同缸”视作育幼的必要条件。

Overview
Crenicara latruncularium is usually a fairly peaceful cichlid, but breeding changes its social behavior. A female guarding her cave may drive away even the male, so ordinary community compatibility does not necessarily continue through brood care.
Distribution & habitat
It is native to the Guaporé drainage in western Brazil and the Mamoré in Bolivia.
Aquarium setup
Provide dense plants with wood, rocks, and floating cover. A spawning cave is useful for breeding, together with space for other fish to leave the guarded area.
Diet & feeding
Quality cichlid pellets or flakes can form the staple. Vary these with live and frozen foods, and include a plant component such as algae wafers or spirulina flakes.
Behaviour & compatibility
Outside breeding, peaceful small characins, rasboras, and small catfishes can be suitable companions. Once a pair breeds, the female's defensive behavior intensifies and earlier peaceful coexistence should not be assumed to continue.
Sexual dimorphism
Males grow larger, show stronger color, and have prominent blue markings near the gills. Their dorsal and anal fins are also more extended.
Breeding
Eggs are placed in a cave. The female defends the site against approaching fishes, including her partner. Hatching takes about three days, followed by another four or five days before the young swim freely. Remove the male if the female attacks him at this stage. Fry take newly hatched Artemia and can gradually move to suitably sized adult foods as they grow.
Notes
Keeping both adults together is not an essential part of raising the brood when the guarding female rejects the male.
