Best fish for 3 gallon tank

As the only aquarium fish, Betta Splenden fighting fish can be kept in a small 3 gallon aquarium. The beautiful animals live in the rivers of their native Bali / Indonesia in small areas. They are very popular in the aquarium hobby and are often sold as beginner fish, which are then socialized in the community beginner tank. There the animals suffer from stress, as they are kept with other aquarium fish that are usually not suitable for them. Fighting fish should not be socialized with each other: in the wild, male and female Bettas are grouped together only for breeding, where even the breeding of young animals is carried out exclusively by the male.
