This species is very similar
and therefore is mistaken and sometimes labeled as
this species. The main differences is that C.
musaicus does not have a white spot/blotch underneath
the dorsal fin and has a different pattern on the
caudal fin from this species. Habitat:
Centromochlus orca is known from the mouth of
igarapé Jamari, a tributary of the lower rio
Nhamundá, in the western Pará, and from
two close localities in lagoa Sete Ilhas upstream
from Nhamundá, on boundary between Amazonas
and Pará, in a region along the transition
between the Amazonas floodplain and the Guiana Shield.
Note: Regarding the dubious position
of C. musaicus within available genera of
Centromochlinae, a reappraisal of phylogenetic relationships
within the subfamily is in preparation (LMSS). Based
on this ongoing study of centromochlin catfshes, there
is some evidence that C. musaicus and C.
orca are sister species in a more inclusive Centromochlus
clade. In this paper we retain C. musaicus
in Tatia to avoid confusion, but consider
Tatia to be a paraphyletic assemblage (Sarmento-Soares
et al 2016). See Bárbara B. Calegariet. al. 2019 for further update. "Sp.
Ninja" was described (Dec. 2016) as Centromochlus
orca due to the colouration resembling that of
the orca whales (Orcinus orca). Aquarium
Care: This small driftwood cat would probably
be best kept in the same conditions as Centromochlus
musaicus and 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. Remarks:
Mees (1974) assigned this species to Tatia
but Ferraris (2007) reverted it back to the original
genera of Centromochlus. Just recently (September
2019) a new paper was released by Bárbara B.
Calegariet. al. whereas this species
was reclassified back to Tatia again.
