Gold Fish & Koi

Gold Fish & Koi

Knollwood does not sell fish for ponds, but we do recommend them! Besides being delightful to watch, they complete the ecosystem-balance of your pond and help control unwanted plant and insect growth.

We do carry fish food and fish-safe pond treatments for your convenience.

The general cause of algae in ponds is excess nutrients from either the overstocking or overfeeding of fish, overfertilization of plants, or too few plants in the pond. A general rule for stocking fishponds is to use 4-6 goldfish and one water lily for every square yard of water surface, or one inch of fish for every 3 gallons.

In all but the smallest ponds, frogs and tadpoles should not need any additional food. If sufficiant plants are not available, very small amounts of steamed lettuce may be given. Provide places for them to crouch slightly submerged when fully grown. Water must be clean pond/creek water: tapwater must stand 5-7 days before putting your tadpole in, or adding more water to the pond.
