 Relevant Information:

This species is very similar to Tatia musaica and therefore is mistaken and labeled as this species. The main differences is that T. musaica does not have a white spot/blotch underneath the dorsal fin and has a different pattern on the caudal fin from this species. Aquarium care: This small driftwood cat would probably be best kept in the same conditions as Centromochlus perugiae 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: "Sp. Ninja" has now been described (Dec. 2016) as Centromochlus orca due to the colouration resembling that of the orca whales (Orcinus orca). 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. Further Remarks: Regarding the dubious position of T. musaica 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 T. musaica and C. orca are sister species in a more inclusive Centromochlus clade. In this paper we retain T. musaica in Tatia to avoid confusion, but consider Tatia to be a paraphyletic assemblage (Sarmento-Soares et al 2016)
