Description

If you want a peaceful centrepiece for a warm community aquarium, the Cobalt Dwarf Gourami is one of the most eye-catching choices in the aquarium hobby. This all-blue colour form of Trichogaster lalius, often listed as Trichogaster Lalius «Cobalt», combines metallic colour, manageable size, and fascinating labyrinth-fish behaviour. Unlike many small fish, it can breathe atmospheric air using a specialised labyrinth organ, which means it often glides to the surface in a calm, deliberate way that adds real character to the tank. Adult cobalt dwarf gourami size is usually around 5-6 cm, with a lifespan of about 4 years when kept in stable conditions.

如果您想为温和的社区型水族缸增添一个引人注目的“主角”，那么“钴蓝矮丽鱼”（Cobalt Dwarf Gourami）绝对是水族爱好者眼中的绝佳选择之一。作为毛足鲈（*Trichogaster lalius*）的一种全蓝色变体（常被标注为 *Trichogaster lalius* “Cobalt”），它兼具金属般的光泽、适中的体型，以及迷人的迷鳃鱼类行为特征。与许多小型鱼类不同，它拥有一种特殊的“迷鳃”器官，能够直接呼吸空气；因此，它常会以一种从容、优雅的姿态游向水面换气，为整个水族缸平添了几分独特的灵动与个性。成年钴蓝矮丽鱼的体长通常在 5 至 6 厘米左右；在环境稳定的条件下，其寿命约为 4 年。
