in the only member of this genera and is found in
the Rio Tocantins where it gets its genus name from.
Misleading reports in some aquatic literature and
the internet as being of a small size but this is
quite a large Auchenipterid, so tankmates would need
to be chosen carefully. Remarks:
The last two thumbnail images were captured by Mark
Henry Sabaj and he explains here:- "Tocantinsia_piresi_ANSP195482_t2500
measures 38 cm standard length and is from Rio Xingu
(middle Volta Grande), off left bank, ca. 54 km southeast
of Altamira. This species is a dweller of large river
channels with juveniles found at great depths during
the low water season."
