The Fire Ant Tetra is a relatively new species, only discovered in 2017. These Tetras are a truly unique South American characin that exhibits sexual dichromatism.
Fire Ant Tetras may be kept in a community aquarium; however, due to their small size and timid nature, you should only keep them alongside other small, small Characins.
Fire Ant Tetras are a schooling species in nature; therefore, it would be best to keep these fish in a group of 10 or more individuals for their comfort and overall appearance. In addition, keeping these Tetras in more significant numbers will give your aquarium a more natural-looking display.
