Giant goldfish drifting past apartment windows

A gigantic goldfish glides past rows of lit windows while laundry sways in its wake. Only the fish is impossible: the building, the sky and the light stay real, which is what makes the clip believable. Vertical 9:16, 8 seconds.

Vertical 9:16, 8 seconds. Shot from the street looking up at an apartment block at sunset: a gigantic [ANIMAL, e.g. orange goldfish] drifts slowly past rows of lit windows, its fins rippling like silk, reflections sliding across the glass, laundry on a balcony swaying in its wake. Realistic scale and lighting, no people visible. Sound: soft city evening, a gentle underwater-like whoosh.

Let only one thing be impossible and keep the building and sky real. “No people visible” stops odd faces appearing in the windows.
