Koi, scientifically known as Cyprinus rubrofuscus, are ornamental varieties of domesticated carp. These fish are celebrated for their beauty, size, and colour patterns, making them prized inhabitants in outdoor ponds and water gardens.
Pond Requirements
- Size: A minimum of 1000 gallons is recommended to provide adequate swimming space and maintain water quality.
- Depth: At least 3 feet deep to accommodate their size and protect them from predators and harsh weather.
- Filtration: A high-capacity filtration system handles the significant bioload and keeps the water clean.
- Aeration: Adequate aeration to ensure sufficient oxygen levels in the water.
Water Parameters
