Koi are often regarded as the king of ornamental pond fish. Very popular and attractive, they grow big and fast, and are only recommended for large, well maintained ponds. Koi can grow to around 90cm in length (excluding the tails) and if looked after properly they can become quite tame. Available in a wide range of mixed colours including red, yellow/gold, blue and black.
Consumer guidance:
Make sure you give Koi plenty of space in garden ponds. Being a coldwater fish, they require more oxygen so do not over stock these species. Stocking density is defined by the surface area (oxygen intake capability), not the total water volume.
In outdoor ponds, (based on a correctly filtered set up) it is recommended that you do not stock more than 10 Koi per 10,000 litres.
Depth is critical too, a depth of at least 120cm is suggested to help the fish rest over winter.
Common name(s): Koi, Koi Carp,
Scientific name: Cyprinus carpio
Other names: none
Native habitat:
• Captive bred for the ornamental fish industry
Potential lifespan:
• 30 years or longer
Maximum size (approx.):
• 90cm.
Degree of difficulty to keep:
• Moderate, for slightly more experienced fishkeepers.
Swimming level:
• all areas.
Breeding:
• Egg scatterer.
Sex:
• Adult females are fuller bodied, whereas adult males are more sleek.
• Adult males in breeding condition exhibit breeding nodules on pectoral fins & gill plates.
Temperature:
• Can tolerate temperatures from 2 to 32°c.
Water parameters:
• pH from 7 to 8.5,
• Hardness 5 to 25°dGH
Feeding:
• Good quality floating pellets/sticks as their staple diet, mixing with growth enhancing types in the summer months. Feed wheatgerm or cold weather food only in the winter.
• Offer a treat of dried shrimps or silk worm pupae in the summer.
Minimum recommended pond size:
• 10,000 litres and must be at least 1.2m deep.
Cohabitation:
• Suitable to keep with all other non-predatory pond fish and other Koi varieties.
• Care needs to be taken when feeding, especially with larger specimens. Make sure any smaller fish and any Sturgeon/Sterlets get their fair share of food too by feeding them in separate area of the pond.
Other tips and information:
• It is probably best not to have plants as Koi love to dig and root around, eating plants along the way. Any underwater plants will need to be in large pots, and ideally well established (at least a year or more) and covered with large stones or pebbles. They are still not guaranteed to be safe though.
• Live plants can used but they are prone to getting eaten. Water Cress (Nasturtium Aquaticum) is worth a try though, it is supposedly distasteful to fish.
• Provide good filtration and oxygenation.
