Giant Koi Balloon Over Glowing Algae Wake

Midday mountain light cuts through ground fog pooling in the valley floor, illuminating a narrow river channel. A rowing boat leaves a trail of bioluminescent algae that pulses with electric blue and teal hues against the dark water. Suspended high above the water surface, a massive koi fish floats like a living parade balloon, its orange scales and flowing fins rendered with sharp, legible detail. The fish hovers parallel to the river bank, casting a faint, soft shadow on the mist below. Along the water's edge, late spring vegetation shows fresh green shoots and small yellow wildflowers growing in the damp soil. The glowing wake curves sharply around the boat's hull, creating a luminous ribbon that contrasts with the pale, dry mountain light filtering through the haze. The fish's tail fin appears to ripple in a breeze that does not move the water beneath it.
