The Koi Fish
Following the unexpected disappearance of the water lilies, Oliver grew increasingly cautious to prevent a similar fate from befalling his beloved Koi fish. Determined to safeguard them, he devised a strategy: he opted to acquire Koi fish with distinct appearances, enabling him to distinguish them from one another easily. By introducing a variety of visually unique fish, Oliver hoped to keep track of each individual and ensure their safety.
