The Betta, also known as the Siamese Fighting Fish, is easy to care for because they do not require much tank maintenance or a huge aquarium, making them a favorite of both beginning and advanced hobbyists. We recommend at least a 5-gallon tank for your Betta to thrive. If you decide on a community, a larger tank will mitigate the chances of aggression. In addition, you should use low-flow filters, like sponge filters, in your tank, so your fish dont struggle to swim. Female Betta fish do well in whats known as sororities and get along well with other tank mates if provided with a large enough tank. Just keep an eye on them and watch out for missing scales or ripped fins on their neighbors. Male bettas can not be housed with other male bettas due to their aggression but can be housed with some other community fish when kept in the right conditions.All pictures shown are for illustration purposes only.
