At a glance the quick version
Looks how to spot one
Scaled, robust cyprinid (fully scaled, mirror, linear or leather forms)
A heavy, powerful fish with a long dorsal fin, a downward-facing mouth and two pairs of barbels. The fully scaled form has large shiny scales, while mirror carp carry a few big mirror-like scales, linear mirrors have a single row along the side and leather carp are almost scaleless.1
Personality what they are like
Peaceful and sociable. Carp are curious foragers that spend much of their time rooting along the bottom.1
Daily activity how busy a day looks
Active, especially at dusk, dawn and night, and constantly forages through soft sediment. It needs a lot of room to swim and grow.12
Grooming and care the hands-on bits
Copes with a wide range of conditions: about 3 to 35 C (best 23 to 30 C) and pH 6.5 to 9.0. A large, well-filtered pond keeps the water clear despite its digging.12
Home where they are happiest
A large pond or lake with soft bottom and plants. FishBase advises against home aquariums, saying a tank over 2 m long would be needed for a group. Pond carp should never be released into the wild.21
Food basics what goes in the bowl
An omnivore that sifts the bottom for insect larvae, worms, crustaceans and molluscs and also eats plants and seeds. Pond fish take sinking carp or koi pellets.12
Company who they like around
The story where it all began
Romans kept carp in purpose-built ponds about 2000 years ago, and between the 13th and 16th centuries monks spread carp farming across Europe. In East Asia carp were farmed from early times too, and Japanese breeders later developed the coloured carp that became koi.1

Owner questions the things everyone asks
How often should I feed my Common Carp?
Furry Diary's starting plan is to feed once daily, but only during the warm season when the fish are active. In cooler weather, reduce or stop feeding as their metabolism slows. Always follow the food label and check with a vet for exact amounts.12 Furry Diary plan
What does a Common Carp eat, and what should it never eat?
Common Carp are omnivores that enjoy insect larvae, worms, crustaceans, molluscs, plants, and seeds. Sinking carp or koi pellets are a good staple. Never feed them bread or processed human foods, as these can harm their health.12
How much space does a Common Carp need?
Common Carp need a large pond or lake with a soft bottom and plants, as they grow big and are active swimmers. FishBase advises against home aquariums, noting a tank over 2 meters long would be needed for a group. A spacious pond is best.12
What temperature, light or water does a Common Carp need?
Common Carp cope with a wide range: water temperature from about 3 to 35°C (best 23 to 30°C) and pH 6.5 to 9.0. They need a large, well-filtered pond to keep water clear despite their digging. Natural light is fine, but avoid extreme heat.12
How often should I clean a Common Carp's home?
Furry Diary's starting plan suggests a daily pond check, a water test every two weeks, and a filter clean every month. Regular cleaning keeps the water healthy, but avoid over-cleaning as carp like some natural sediment. Furry Diary plan
Can a Common Carp live with others?
Yes, Common Carp are peaceful and sociable schooling fish that prefer groups of five or more. They get along well with other pond fish of similar size and temperament.12
How long does a Common Carp live?
Common Carp can live a very long time, with a known maximum lifespan of 64 years. With good care in a spacious pond, they often live for many decades.12
Can I handle a Common Carp?
Handling is not recommended as Common Carp are heavy, powerful fish with barbels and scales that can be damaged. They are best observed in the water to avoid stress or injury.1
