概述
Melanotaenia splendida rubrostriata 是色彩鲜明的彩虹鱼类型，幼鱼通常远不如成鱼绚丽，发色可能超过一年。它活跃又有些胆怯，同种群体和足够游泳空间有助于展现自然状态。
分布与栖息地
分布于印度尼西亚和巴布亚新几内亚，常在沿海平原河流的支流与沼泽中活动，借水草和其他水下残体遮蔽。
饲养环境
密植水草与开阔游泳区并存，水流宜轻缓。不同产地的酸碱条件有差异，未知采集地时以接近中性的水作饲养起点较合适，不必追求某一极端水况。
食性与喂食
通常不挑食，多数干粮、冷冻饵和活饵都可接受。经常补充活饵有助体色表现。
习性与混养
建议至少六至八尾群养，更多同种可进一步减轻胆怯并促进雄鱼展示，但需要相应放大空间。它虽温和，迅速游动和体形仍可能让小鱼或慢游鱼紧张。
可考虑体形相仿的彩虹鱼、脂鲤、斑马鱼、鲃类、淡水虾虎和合适鼠鱼。不要与容易杂交的近似类型或亚种混养。
雌雄区分
雄鱼成熟后较大、体色较浓，身体比雌鱼更高，背鳍和臀鳍延长；雌鱼腹部在繁殖状态下明显饱满。
繁殖
是散卵型，产卵相对容易，鱼苗较难带大。准备无底砂的繁殖缸、细叶水草或产卵拖把及小型气动过滤；亲鱼另缸成群调养，多喂活饵和冷冻饵。选择饱满雌鱼和发色良好雄鱼配对，轻微升温可能引发产卵。
鱼可连续数周每天产出一批带附着细丝的卵。成鱼通常不吃卵，但把卵定期转入使用亲鱼缸水的独立育苗缸更便于管理。孵化约需 7–12 天，初期用纤毛虫类开口，约一周后再转丰年虾无节幼体等可游动食物。鱼苗贴近水面，沉底饵不适合。
补充说明
不同产地的颜色与斑纹有变化，保留产地信息对识别及繁殖管理都有价值。幼鱼颜色淡并不代表其成年后也会如此。

Overview
Melanotaenia splendida rubrostriata develops striking adult coloration, but juveniles can remain comparatively dull for more than a year. Activity and a tendency to nervousness make a proper group and generous swimming room important.
Distribution & habitat
Found in Indonesia and Papua New Guinea, it uses coastal-plain river tributaries and swamps, sheltering among vegetation and submerged debris.
Aquarium setup
Create planted refuges alongside open lanes and keep the current gentle. Native pH conditions vary by locality; when origin is unknown, approximately neutral water is a sensible starting point rather than targeting an extreme.
Diet & feeding
Most suitable dry, frozen, and live foods are accepted. Regular live-food additions support strong coloration.
Behaviour & compatibility
Keep at least six to eight together, preferably more with sufficient space. Groups reduce skittishness and encourage male displays. Peaceful behavior does not prevent its speed and size from unsettling smaller or slower fish.
Similar-sized rainbowfishes, characins, danios, barbs, freshwater gobies, and suitable cory catfish are possibilities. Keep related forms that could hybridize separate.
Sexual dimorphism
Mature males are larger, brighter, and deeper-bodied than females, with longer dorsal and anal fins. Females become noticeably full in the abdomen when ready to spawn.
Breeding
Breeding involves egg scattering and is usually easier than raising the fry. Use a bare-bottom tank with fine plants or mops and a small air-powered filter. Condition adults as a group elsewhere on live and frozen foods, then pair a full female with a strongly colored male. A small temperature increase may stimulate activity.
Eggs attach by fine threads and can be laid in daily batches for several weeks. Adults generally leave eggs alone, but moving them regularly to a separate nursery with matching parental-tank water simplifies rearing. Hatching takes roughly 7–12 days. Start with infusoria, then introduce free-swimming foods such as Artemia nauplii after about a week. The young stay near the surface, where sinking food is ineffective.
Notes
Local populations vary in pattern and color. Keeping their origins documented helps identification and breeding management; a subdued juvenile is not a reliable preview of the adult.
