This Dorad has been known in
the hobby for many years as Platydoras
we now know that this species has never, or very rarely
been exported and as such the species that we thought
was P.costatus is actually Platydoras
P. costatus originates from the coastal drainages
of Suriname and French Guiana (i.e., Corantijn, Suriname,
Maroni) and lacks a distinct light stripe on the head
and sides. There are four recognised species of
Platydoras: P. armatulus (Paraguay-Paraná
and portions of Amazon and Orinoco basins), P.
costatus (Corantijn and Maroni basins), P.
brachylecis (Rio Mearim, rio Pindaré,
rio Itapecuru and rio Parnaíba basins in northeastern
Brazil) and P. hancockii (Negro, Essequibo,
Demerara, and upper Orinoco basins). In common
with most of the Doradidae family it can create a
sound by grating its fin bones in each socket and
amplifying the noise via the swim bladder which is
one reason why it got its common name of the Chocolate
Talking Catfish. Aquarium Care:
This is a fairly easy catfish to keep as long as you
can provide it with shelter such as pipes or cave
work. It will even jam itself into the pipe with its
pectoral spines and will be unremovable. Diet:
Easy to feed on frozen food such as bloodworm, tablet
and pellet foods. In youngsters it is better to feed
at night after lights out, the older they get they
will get bolder and come out at feeding time.
Paraná River basin. Type locality:
Brazil, le Parana, mais non au-dessous du 27º30'
de latitude sud.
