About Hibuna (Red Crucian Carp)

The Hibuna is a red or orange crucian carp, not a goldfish. Learn its traits, beginner-friendly care, and what to know before bringing one home.

7 things to know before welcoming a Hibuna (Red Crucian Carp)

1. 1A Crucian Carp, Not a Goldfish

   The Hibuna is not a goldfish variety but a color mutation of the Ginbuna-type crucian carp. Without black pigment it appears red or orange, and its body stays slim and carp-like. If you are expecting the flamboyant look of a fancy goldfish, check the photos carefully before you decide.

2. 2Never Release Into the Wild

   The fish in circulation are captive-bred, and the Hibuna habitat at Harutori Lake in Hokkaido is a national natural monument. They must not be released into the wild, so think through what you would do if you could no longer keep one before you bring it home. Caring for the fish for its whole life is a basic requirement.

3. 3Plan for a Large Fish

   Data on the adult size of the Hibuna is limited, but as a crucian carp it grows large. Even if you start with a small fish, plan for growth and think about the space you will need later.

4. 4Roomy Tank and a Lid

   Because it may grow large, a roomy tank or container makes it easier to keep the water stable. Crucian carp can leap when startled, so cover the top and close any gaps. Choose the spot with the weight of a filled tank and the amount of sunlight in mind.

5. 5Focus on Water Quality

   Crucian carp tend to eat and excrete a lot, so the water can foul quickly. Set up good filtration and change part of the water regularly to keep it clean. Feed small portions that are eaten up, so that no leftovers remain.

6. 6Choose Tank Mates Carefully

   Temperament varies between individuals, but like other crucian carp they move quickly. Small fish that fit in their mouths may be eaten, so pair them with fish of a similar size. Even with goldfish or other companions, watch to make sure everyone gets enough food.

7. 7Health Checks and Lifespan

   There is little lifespan data specifically for the Hibuna, so a number of years cannot be stated. Expect a long commitment and observe your fish every day. If you notice white spots, injuries, or clamped fins with little movement, review the water quality and consult the breeder you bought from or a veterinarian who knows fish.
