The Congo Tetra are a stunning fish, with an iridescent blue/ green body and a striking red line running horizontally from nose to tail. They are a great addition to a community tank.
Tetras are best kept in large schools (minimum 6 in the group) and different species can generally be kept together with few problems. Tetras will also mix readily with a range of species and are generally an ideal community fish – however as many species are relatively small, it is not a good idea to mix them with species that grow large such as Oscars. Some species can be prone to eating aquatic plants
Tetras are the second most commonly kept fish in community tank setups, after livebearers (see our Livebearer Care Sheet for more information on these fish) . They are popular because of their vibrant colours, manageable size, mild behaviour and schooling habits.
