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 U.K. aquarist and amateur
ichthyologist Steven Grant (2015) a new paper was
released by Bárbara B. Calegariet
al whereas this species (C. schultzi),
Tatia carolae Vari & Ferraris, 2013 and
C. macracanthus Soares-Porto, 2000 were
reclassified to a new genus, Balroglanis.
In 2021 this species was reclasified back to the original
genus of Centromochlus by Coelho, F. L.,
C. C. Chamon and L. M. Sarmento-Soares. Reproduction:
They leave their eggs in a gelatinous mass under stones
or bogwood. As of this family the male will fertilise
the female internally. Aquarium Care:
Keeping this 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. Also provide pipework for this genera for a choice
of hiding places. 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.
Etymology: Balroglanis:
Meaning "Balrog Catfish" and is derived
from the Maia, a Balrog known as Durin's Bane, who
terrorised Durin the Deathless' descendants in Khazad-dûm,
in J. R. R. Tolkien's Lord of the Rings legendarium.

Centromochlus
schultzi is endemic to Brazil and widely distributed
in the Xingu, Tocantins, upper Madeira, and upper Tapajós
river basins. It is a naturally common but infrequent
species, occurring in small and medium-sized streams.
Despite several hydroelectric projects in the region,
C. schultzi has been recorded upstream of the
Lajeado hydroelectric plant reservoir. Because no significant
threats to its population have been detected, Centromochlus
schultzi has been classified as Least Concern (LC),
(IUCN 2022).
