Dorsal spines (total): 1; Dorsal soft rays (total):
5; Anal soft rays: 10 - 11; Vertebrae: 34 - 36. Diagnosed
from all other species of Tatia by the following
characters: male anal fin with sharp pointed tip;
the first unbranched anal-fin ray divided into 3-4
segments; and the last branched ray reduced. Can be
distinguished from most of its congeners, except Tatia
aulopygiaTatia intermedia and Tatia
gyrina, by having a wide mouth, width 54.0-59.7%
HL (vs. 39.0-53.3% HL). Additional characteristics
for recognition of Tatia brunnea are diagnostic
in combination: nasal ossified with wide medial flanges
partially sutured to lateral margin of mesethmoid;
ribs 9-10; post-Weberian vertebrae 34-36. Colouration:
Other features useful for distinguishing Tatia
brunnea include details in colouration, such
as: border of mouth whitish, contrasting with dark
head; posterior border of nuchal shield usually whitish
or pale; pectoral-fin spine usually with transverse
bands; caudal fin usually whitish with scattered dark
brown blotches; and head width 86.6-93.4% HL.
Aquarium care: This 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.
