Points to keep in mind when mixing swimmers

Regarding mixed swimming, first of all, the Congo tetra has a mild temperament. Therefore, when you keep Congo tetras, you will find that they swim in groups compared to other ornamental fish.Congo tetras swim in groups for defense by making them look like large fish by swimming in groups and for measures to ensure the survival of as many fish as possible if they are attacked. Among freshwater ornamental fish, there are not many varieties that swim in groups, so we recommend this species to those who want to see them swim in groups. They are also mild-mannered and unlikely to harm other fish. On the other hand, if the species you wish to mix with the Congo Tetra is a species that is territorial and will harm other fish, it will be the first to be harmed, so be sure to investigate this beforehand.

Points about spawning
Many people who keep Congo tetras want to breed them. The Congo Tetra has a lifespan of about two years, so the time until it is ready to breed is short, approximately four to six months after birth. This means that if you want to breed them, it is important to choose relatively young individuals when purchasing them from specialty stores. In addition, Congo tetras need to be carefully identified as male and female.The next step is to prepare a breeding tank. If the parents (adults) and fry (young) are kept in the same tank after successful spawning and hatching, they may compete for food or the adults may eat the fry, resulting in a decrease in the number of fry. To prevent this from happening, we recommend keeping the parents and fry in separate tanks for easier management by humans.

The Congo tetra is a very weed-eating species, so be careful not to keep it in an aquarium with mainly aquatic plants, as it will quickly become useless.If you do not want them to be eaten, we recommend that you choose a species such as "Anubias nana" whose leaves themselves are hardy.
