接吻鱼（学名：Helostoma temminckii），正式名称吻鲈，又名Kiss鱼、吻嘴鱼。属于鲈形目攀鲈亚目沼口鱼科沼口鱼属，是观赏热带鱼的知名品种之一。原产于印度尼西亚爪哇岛和马来西亚等地。野生种成鱼可长达20-30厘米，家养后鱼体变小为10厘米左右。

接吻鱼嘴呈喇叭形，以接吻而闻名，两条接吻鱼之间可发生如人类接吻一样的动作，时间长达数分钟。但这并非是表示亲热，而是争夺领地的行为。现已难见作为宠物饲养的接吻鱼接吻。除了具观赏价值之外，接吻鱼亦可食用。

These fish originate from Thailand to Indonesia. They can be food fish which are farmed in their native Southeast Asia. They are used fresh for steaming, baking, broiling, and pan frying. The kissing gourami is a popular aquarium fish.
