Dorsal spines (total): 1; Dorsal soft rays (total):
6; Vertebrae: 35 - 37. Dorsal fin with 6 branched
rays; dorsal and pectoral-fin spines with filamentous
extensions. Anal fin with 4-5 simple rays, 7-9 branched
rays. Snout strongly projecting. Nasal barbel reaching
only to posterior margin of orbit; maxillary barbel
reaching to end of pelvic fin or to anal-fin origin;
maxillary barbel membrane with narrow attachment to
cheek and broad attachment to corner of mouth; mental
barbels reaching posteriorly to end of head. Vent
opens into pouch or pseudovent, with broad membranous
opening near pelvic fin tip. Head, body and caudal
peduncle slightly more elongate than other congeners.
Aquarium Care: An aquarium having
a tight fitting cover glass is best, as they do have
a tendency to regularly swim vigorously from the substrate
to the surface of the water. It is essential that
good filtration is provided; and a internal power
filter that has quite a good flow of water, and an
air diffuser fitted is recommended in order to go
someway in providing turbulent and well oxygenated
water which is a must if one wants to keep Nangra
assamensis alive and healthy for any length of
time. A substrate of fine rounded gravel interspersed
with stones and rocks and a few clumps of short hard
leafed plants would go someway in making this small
sisorid feel secure. Diet: Feeding
in not too problematic as it takes well to the usual
frozen foods such as daphnia and bloodworms. Remarks:
Like other members of the Sisorid family Nangra
posses an adhesive apparatus in the form of visible
pleats of skin on their ventral surfaces.
