雄性斗鱼在一个透明玻璃水族箱中照顾他的气泡巢，水族箱里还有一盆绿色的发财树。

The fish, with its dark body and red fins, hovers beneath the white bubble structure, surrounded by the vibrant green leaves and roots of a money plant growing in the clear glass aquarium. This intimate view highlights the natural breeding behavior of the Siamese fighting fish.
