Adding water features to a garden is one of the most rewarding ways to transform outdoor spaces. The soothing sound of running water, the beauty of aquatic plants, and the calming presence of fish can turn an ordinary yard into a personal retreat. But when planning a pond, many homeowners face a key question: should you build a traditional fish pond (or water garden), or invest in a koi pond? Each option has unique benefits and challenges, and the right choice depends on your lifestyle, budget, and long-term goals.
In this guide, we will break down the differences between fish ponds and koi ponds, explain what sets them apart, and help you decide which one suits your garden best in 2025.
What Is a Fish Pond (or Water Garden)?
A fish pond, often called a water garden, is a shallow pond designed primarily for aesthetics and light aquatic life. It emphasizes plants, tranquility, and natural balance.
Key Features of a Fish Pond
- Depth: Typically 1 to 3 feet deep, making it easier to build in small gardens.
- Plants: Aquatic plants act as natural filters, maintaining water clarity.
- Wildlife: These ponds often attract birds, butterflies, and frogs, creating a natural ecosystem.
- Fish: Goldfish and other small species may be added, but they are not the central focus.
- Filtration: Minimal; many water gardens can function with simple pumps or no mechanical system at all.
- Cost: Lower installation and maintenance costs compared to koi ponds.
Best For
A fish pond is perfect for homeowners seeking a serene, plant-rich space with low upkeep. If your goal is to enjoy water lilies, lotus flowers, and a peaceful environment without major responsibilities, a water garden is an excellent choice.
What Is a Koi Pond?
A koi pond is designed specifically to house koi fish, which are ornamental carp known for their vibrant colors and cultural significance. Unlike casual fish ponds, koi ponds are engineered to sustain these fish long-term.
Key Features of a Koi Pond
- Depth: Usually 3 to 6 feet to protect koi from predators and temperature fluctuations.
- Filtration: Advanced systems, including both mechanical and biological filtration, to handle fish waste and maintain water quality.
- Aeration: Strong circulation and aeration are required to provide oxygen and keep koi healthy.
- Construction: Built with koi safety in mind, including smooth edges, predator deterrents, and durable liners.
- Fish: Koi are the centerpiece, often becoming pets with lifespans of 20 years or more.
- Cost: Higher upfront investment and ongoing maintenance requirements.

They require dedication, but the reward is a dynamic, living display of vibrant fish that becomes the focal point of the garden.
