Description:Distinguished from all other species of Tatia
by having a short cranial fontanel, with the opening
restricted to the frontals, a genital papilla with
thick flap of skin around the deferent duct in males
(Fig. 9); and a notched anal fin in adult males (Fig.
9). The species also is distinguished from congeners
by a combination of characteristics: nasal bone partially
sutured to lateral margin of mesethmoid; anal fin
with 7-8 branched rays; 10-11 ribs; 38-39 post-Weberian
vertebrae. Additional features useful for distinguishing
this species include: third nuchal plate well projected
laterally with curved tip; and caudal-fin lobes of
mature females similar in length, but mature males
with slightly elongated upper lobe. Colouration:
Body colouration is somewhat variable, usually with
large bands or blotches irregularly distributed over
sides of body. In some specimens coloration is uniformly
dark or pale brown, with caudal fin mottled. Some
young specimens have small spots over ventrolateral
parts of body and a barred caudal fin. Aquarium
Care: Give them small pipes, and they do
seem to like to hide in the crevices of bogwood as
well. They appear to be happier if they can jam themselves
in with the use of their pectoral fins. Community
tanks are fine for this species although you may find
that they will predate on fry from other species,
but apart from that they come well recommended but
don't expect to see them too often. Diet:
In its native habitat they feed on small invertebrates
and crustaceans and in the aquarium they will eat
anything given such as frozen bloodworm inserted in
to their hideaway, catfish tablets, white worm (sparingly)
and prawns and shrimp. They do like their food and
you can see them shooting out of their hideouts and
swimming in a frenzied manner to try and take all
for themselves, especially when you feed them their
favourite food, frozen bloodworm. Etymology:

The specific name aulopygia: aulos, tube
