Particularly prolific throughout the lower Congo River, A. caudalis, is popular in the hobby for their hardiness, lively personalities, and peaceful temperaments. Also known as ‘Yellow-tailed Congo Tetras’ they reach just over 2 inches in length, have silver arrow-shaped bodies, and yellow caudal fins with a black stripe down its center. Tank setup should resemble river habitat, with substrate of variable-sized rocks and boulders, sand, and gravel, driftwood roots and branches, current, and lots of open swimming space. A schooling fish by nature, they should be kept in groups of 8-10 conspecifics, and can be kept alongside many other species inhabiting similar environmental conditions. Good tank-mate candidates include similarly-sized cyprinids, dwarf cichlids, loaches, and catfishes. In the wild, these tetras mostly consume small invertebrates and fallen fruit. In captivity, they happily feed on high quality flakes and granules, with regular supplementation of live and frozen offerings like bloodworm and daphnia. Tank waters should be maintained with temperatures of 71 to 79°F, pH between 5.0 and 7.5, and hardness of 36 to 268 ppm.
