Our koi betta for sale each have unique markings, and their striking appearance and energetic personality make them a popular choice for aquarium enthusiasts.

Location

This koi betta is native to Southeast Asia, where it can be found in shallow waters like rice paddies, ponds, and slow flowing streams. These warm, tropical waters are perfect for their vibrant colours to thrive.

Diet

Koi bettas are carnivorous and require a diet rich in protein. Offer them high quality betta pellets, along with occasional live or frozen foods such as bloodworms and brine shrimp to ensure they stay healthy.

Care

These Bettas do well in water temperatures between 24 and 30°C. They can be territorial, especially males, so it’s best to keep them alone or with non-aggressive tank mates in a peaceful aquarium setting. Never keep two males together.

Habitat

In the wild, koi bettas prefer shallow, slow flowing waters with plenty of plants and hiding spots. Recreate this environment by adding live plants and using a gentle filtration system to keep the water calm.

Breeding

Breeding koi bettas involves the male building a bubble nest. After fertilization, the male guards the eggs until they hatch, with the fry needing a separate tank for safety and growth.
