Mees (1974) assigned this species to Tatia but Ferraris (2007) reverted it back to the original genera of Centromochlus. Just recently (September 2019) due to earlier work carried out by Steven Grant (2015) a new paper was released by Bárbara B. Calegari et. al. whereas this species (C. macracanthus), Tatia carolae Vari & Ferraris, 2013 and Centromochlus schultzi Rössel, 1962 were reclassified to a new genus, Balroglanis. Dorsal spines (total): 1; Dorsal soft rays (total): 5; Anal soft rays: 7; Vertebrae: 37. First nuchal plate absent; the supraoccipital bone sutured to the 2nd nuchal plate. First dorsal fin spine elongated, 28-35% SL. Coracoid process covered with skin, not visible externally. Aquarium Care: Keeping this rare species is not too much of a problem as long as the water is kept clean and not too alkaline with a p.H.of between 6.5 and 7.0. They do like a planted aquarium where they like to hide during the day. Diet: In its native habitat they feed on insects, mostly ants, beetles, and mayflies and in the aquarium they will eat anything given such as frozen bloodworm which they will come out of hiding to feed on, catfish tablets, daphnia, white worm (sparingly) and any other worm-like foods. Breeding: They leave their eggs in a gelatinous mass under stones or bogwood. As of this family the male will fertilise the female internally.
