Colorful koi cluster and feed in dark Đà Nẵng waters

A school of colorful koi fish swim in dark water. The fish are predominantly orange, white, and yellow. Some of the fish appear to be feeding as they are clustered together and creating ripples on the surface of the water. A large green leaf is visible in the lower left corner of the frame. The water is dark and appears to be disturbed by the movement of the fish and possibly a water feature.
