Koi Betta Summary
Koi bettas are not a blend of koi and betta fish but fall under the Betta splendens category. Their distinct coloration, reminiscent of treasured koi, sets them apart.
This variety was accidentally discovered in the 1970s by Orville Gulley, an inmate at Indiana State Prison, during a rehabilitation project using peanut butter jars for breeding. Once recognized, they were introduced to the world by hobbyist Walt Maurus.
Though pricier, their stunning appearance makes them a prized choice for aquarium enthusiasts.
Koi Betta Appearance
Koi bettas stand out in the world of fish for their unique and varied markings. While marble bettas typically exhibit two marbled shades over their base color, Koi bettas can proudly boast up to three.
These stunning creatures are adorned with Koi-like patterns in a rich spectrum of black, white, orange, red, and sometimes blue. Male Koi bettas can flaunt either long or short fins and are often seen with half-moon, plakat, delta, or veil tail fin types. On the other hand, female Koi bettas, like their betta counterparts, possess shorter fins but don’t lag in displaying vibrant hues.
It’s fascinating to note that a Koi betta’s color pattern can shift with changes in its environment, its mood, and as it ages.

However, their longevity greatly hinges on their living conditions. A high-quality diet, optimal tank environment, and attentive husbandry are essential.

Koi Betta Fish Care
- Tank Size:Â It is strongly advised to provide your Koi Betta with a tank that holds at least 5 gallons of water. This ensures an environment where your betta can move freely and engage in natural behaviors.
- Temperature Range: Maintaining a consistent water temperature of 75–82ËšF is vital for your Koi Betta’s well-being. Extremes below 75ËšF or above 86ËšF can lead to stress and health issues.
- pH Level: Strive for a neutral pH around 7.0, but understand that Koi Bettas can adapt to a slightly broader range of 6.0 to 8.0. Monitoring and stabilizing the pH helps create a comfortable habitat.
- Substrate:Â Opt for a substrate that supports plant growth and is gentle on your betta’s delicate fins. Smooth gravel or sand are excellent choices, while sharp materials should be avoided to prevent injuries.
- Plants:Â Incorporating live plants is not only visually appealing but also enhances the aquarium’s ecological balance. Suitable choices like mosses, dwarf hair grass, Anubias, Java ferns, and floating plants such as water lettuce provide hiding spots, oxygenation, and a more natural habitat.
- Lighting for betta:Â Emulate the natural day and night cycle by providing consistent lighting. Keeping a regular lighting schedule helps regulate your Koi Betta’s biological rhythms.
- Filtration:Â Employ a filtration system that maintains optimal water quality without creating strong currents. Clean water is crucial for your betta’s overall health, while excessive water movement can cause stress.
Koi Betta Breeding
By adhering to these comprehensive steps, you can participate in the wondrous process of nurturing new life within your aquarium, ensuring the health and vitality of your bettas at every stage.
- Set up a dedicated breeding tank equipped with a heater to maintain a stable temperature and a well-seeded sponge filter for biological filtration. Including a tank divider aids in acclimatizing the bettas to each other.
- House male and female bettas in separate tanks to maintain familiarity without the risk of aggression. Allow a period of around 2 weeks for the male and female bettas to acclimate to the breeding tank environment and to each other’s presence.
- The male will initiate the breeding process by constructing a bubble nest at the water’s surface. This elaborate structure serves as the future home for the eggs. After the female releases her eggs and the male fertilizes them, he carefully gathers the eggs and places them within the bubble nest. The female is then removed and returned to her separate tank.
- Once the eggs hatch into fry, it’s crucial to relocate the male back to his original tank to prevent accidental harm to the newborns.
