In the rio Tocantins drainage,
Tatia is represented by two species, namely:
1877) and T. simplex Mees, 1974 (Ferraris,
2007; SarmentoSoares, Martins-Pinheiro, 2008). Tatia
simplex is poorly understood taxonomically. Its
description was based on a single juvenile specimen
(28.5 mm SL) collected in 1968 at rio das Mortes,
Mato Grosso State, Brazil. Since its original description
by Mees (1974) the species was kept under the name
Centromochlus simplex in taxonomic lists
and catalogues, with geographic distribution reported
only to the type locality (e.g., Ferraris, 2003, 2007).
No additional material of the species was identified
for thirty years, until the generic revision of Tatia
by Sarmento-Soares, Martins-Pinheiro (2008). Although
kept as incertae sedis in Centromochlinae (Sarmento-Soares,
Martins-Pinheiro, 2008: Tab. 1), Tatia simplex
appears as a valid Tatia species in recent
contribution (Calegari et al., 2019). Aquarium
Care: This small driftwood cat would probably
be best kept in the same conditions as other Tatia
speciesand would need a planted tank
with the lighting not too bright. Diet:
Feeding of frozen bloodworm which they will come out
of hiding to feed on, catfish tablets, daphnia, white
worm (sparingly) and any other small worm-like foods.
Still listed in Fishbase (2020) as Centromochlus
