Which fish are best suited For my garden pond?
As with planting a pond it’s best to have a balance of fish, with bottom, mid and surface feeders all doing their own part in the pond's eco-system. Remember some fish such as koi grow very large and are unsuitable in small ponds.
Easiest of the pond fish to keep, being a member of the carp family they can vary in colour from a red to very light gold. They will breed easily producing black young that may turn gold later in the right conditions. Goldfish can grow to 30cm but in normal British conditions they will probably reach 20cm (8in).
Similar to goldfish they come in a multitude of colours including reds, greys and blues.
These most spectacular fish can reach 60cm to 90cm (2-3ft) in size and come in an array of colours and patterns. Unfortunately really only suitable for larger purpose-built ponds with a depth of at least 0.9m (3ft).
From the same family as goldfish, but have bright red patches on a white background.
Very useful bottom feeders, clearing up any uneaten food etc. Once introduced into a pond it’s likely you will not see them often as they stay at the bottom and their olive or green/brown colour tends to blend them into the background. A golden variety is often available.
Orfe can grow up to 40cm (18in) and prefer to be kept in shoals. They are useful surface feeders, keeping the insect population in check. Blue Orfe are sometimes available. Should not be kept in smaller ponds or where there is no pump, as they require plenty of oxygen.
