概述
红苹果（Glossolepis incisus）是成熟雄鱼呈鲜红色的彩虹鱼，活动力强但容易受惊。至少六至八条成群更能表现正常活动和发色，需要充足横向游动空间。
分布与栖息地
来自印度尼西亚新几内亚岛北部仙谷湖及周边水域，常在植物茂密的地方成群活动。
饲养环境
底面积至少约 120 × 30 cm。水草可在局部密植，同时保留开阔泳道，水流保持柔和。适合偏硬、近中性至碱性的条件，不宜按软酸水鱼安排。
食性与喂食
通常不挑食，多数干饲料、活饵及冷冻饵都能接受。规律加入适口活饵或冷冻饵，有利于保持良好体色。
习性与混养
性情温和，但体形和游速可能扰动小型、慢游的缸友。可考虑体形相近的彩虹鱼或其他活跃而温和的鱼，确保水质需求相容。
至少六至八条，更多同伴需要相应增加空间。雄鱼在同种相伴时更愿意展示颜色。
雌雄区分
成熟雄鱼背部更高，只有雄鱼发展出典型红色。相对较凉时更多雄鱼能显红，较暖水中往往由强势雄鱼最明显，不能把一时发色较弱直接判为雌鱼。
繁殖
属于散卵型。先在群体中用活饵、冷冻饵调养，再选体况好的亲鱼配对进入繁殖缸，提供细叶水草或产卵拖把，海绵过滤即可，不一定需要底砂。水质宜略硬、偏碱，轻微升温有时能引发繁殖。
亲鱼可连续数周每天产少量卵，卵由细丝附着在产卵介质上。虽然通常不积极吃卵，每天检查并把卵移到水质相同的育苗缸更方便管理。
卵约七至八天孵化，鱼苗先吃草履虫等微型饵，一周左右逐步转为微虫或丰年虾无节幼体。幼鱼对水质恶化敏感，应少量、频繁换水。
补充说明
不同来源及繁殖品系的发色可能存在差异。判断状态时，应同时考虑性别、成熟程度和群内地位，而不是只追求购入时立刻通体鲜红。

Overview
Glossolepis incisus is a rainbowfish whose mature males develop vivid red coloration. It is active but easily startled. A group of at least six to eight encourages confident behavior and displays, while adequate horizontal swimming room is essential.
Distribution & habitat
It comes from Lake Sentani and nearby waters in northern Indonesian New Guinea, usually gathering around dense vegetation.
Aquarium setup
Provide a base around 120 × 30 cm or more. Combine planted sections with open swimming lanes and keep circulation gentle. Relatively hard, neutral to alkaline water is appropriate; soft, acidic conditions do not suit it.
Diet & feeding
Most dry, live, and frozen foods are accepted readily. Regular inclusion of suitable live or frozen offerings helps maintain good coloration.
Behaviour & compatibility
It is peaceful, but its size and rapid movement can disturb small or slow companions. Similarly sized rainbowfishes and other active, placid species are possibilities when their water requirements match.
Keep at least six to eight, increasing accommodation for larger groups. Conspecific company encourages males to display.
Sexual dimorphism
Mature males become deeper-backed and alone develop the characteristic red color. Relatively cooler conditions allow more males to turn red, whereas warmer water often leaves the strongest color concentrated in dominant males. A pale individual is therefore not automatically female.
Breeding
This is an egg scatterer. Condition adults together on varied live and frozen foods, then select a well-conditioned pair for a separate breeding setup. Fine-leaved plants or spawning mops provide egg sites, with gentle sponge filtration and no essential need for substrate. Slightly hard, alkaline water is suitable, and a modest temperature increase may encourage spawning.
Small numbers of eggs can be deposited daily for several weeks, attaching to the spawning medium by threads. Adults do not usually target the eggs, but daily collection into matching water makes nursery care easier.
Hatching takes roughly seven or eight days. Begin with microscopic foods, moving toward microworms or newly hatched brine shrimp after about a week. Fry are sensitive to deteriorating conditions and need frequent small water changes.
Notes
Color can differ among origins and captive strains. Assess sex, maturity, and social position alongside appearance rather than expecting every newly purchased fish to be immediately bright red.
