概述
印度短鰕虎鱼（Brachygobius nunus）身体有四条黑带，眼部有黑纹穿过，与常被贴上相同名字的其他蜜蜂鱼并不一样。它需要小型活饵、丰富遮蔽和适当同类数量，单种饲养比普通混养更合适。
分布与栖息地
模式产地在加尔各答以南恒河三角洲西侧。较可信的范围是印度、孟加拉国和斯里兰卡，缅甸也可能存在；把它说成遍布东南亚各地的记录并不可靠。
生活在沿海低地的淡水或半咸水环境，包括红树林、河口及潮汐溪流。底部常为泥砂和淤泥，覆盖落叶、树根与沉木。
饲养环境
底面积从约 45 × 30 cm 起步，多安排洞缝与遮蔽，借视线阻隔帮助弱势个体避开持续追逐。过滤宜轻柔，海绵过滤很适合。必要时可用珊瑚砂增加水体缓冲，半咸水环境可用海盐配置，不宜把不同来源个体的环境需求一概而论。
食性与喂食
应准备适口小型活饵，如丰年虾、水蚤等。部分个体能逐渐接受冷冻饵，干粮通常被忽略，不能假定普通颗粒足以维持饲养。
习性与混养
建议单种饲养。雄鱼之间尤其有领域性，至少六条能把攻击压力分散到多个个体，配合遮蔽也更有利于大胆活动和自然行为。
雌雄区分
成熟雌鱼通常更圆，抱卵时腹部饱满尤其明显。
补充说明
除了四条较细的黑体带和穿眼纹，臀鳍支条数等细节也有助鉴定。它并不是贸易中所有“蜜蜂鱼”的通用学名，相关种界仍可能涉及未厘清的近似种。

Overview
Brachygobius nunus has four dark body bands and a black stripe through the eye, unlike several bumblebee gobies frequently sold under its name. Small live foods, plentiful cover, and an adequate group are priorities, with a dedicated aquarium preferable to a general community.
Distribution & habitat
The type locality lies south of Kolkata on the western side of the Ganges delta. India, Bangladesh, and Sri Lanka are the more plausible range, with Myanmar possible but unconfirmed. Broad claims of occurrence throughout Southeast Asia are unreliable.
Habitats include fresh and brackish coastal lowlands, such as mangroves, estuaries, and tidal streams. Mud, sand, and silt are covered with leaves, roots, and submerged wood.
Aquarium setup
Provide a footprint around 45 × 30 cm or more. Numerous retreats and barriers between sight lines allow weaker fish to escape persistent attention. Use gentle filtration, such as a sponge filter. Coral material can provide buffering when needed, while marine salt can be used for a brackish setup. Different origins should not be assumed environmentally identical.
Diet & feeding
Be prepared to supply tiny live foods such as suitable brine shrimp and water fleas. Some individuals learn to accept frozen alternatives, but dried foods are usually ignored. Ordinary pellets should not be assumed sufficient.
Behaviour & compatibility
A species-only aquarium is recommended. Males in particular defend areas against one another. At least six fish help distribute aggression, while ample cover supports confidence and more natural behavior.
Sexual dimorphism
Mature females are generally rounder, especially when carrying eggs.
Notes
The four relatively narrow dark bands and stripe through the eye are useful identification clues, supplemented by fin-ray details. This name is not a general label for all bumblebee gobies, and unresolved species boundaries may still involve additional lookalikes.
