Catfshes
of the genus Parakysis Herre, 1940, are cryptically
coloured and found in small forest streams of Sundaic
Southeast Asia. They have a highly rugose skin with
tubercles all over the body, branched mandibular barbels,
a long, low adipose ridge, and a forked caudal fin.
Description: Dorsal spines (total):
1; Dorsal soft rays (total): 3; Anal spines: 0; Anal
soft rays: 8 - 9; Vertebrae: 30 - 31. Head length
26.5-27% SL; conical head; presence of median concavity
on margin of lower lip; presence of laterosensory
canal pore between inner and outer mandibular barbels,
branched outer mandibular barbels, branches of inner
mandibular barbels separated; deeply forked caudal
fin with pointed lobes; 10 branched principal caudal
fin rays; sparsely pigmented caudal fin; absence of
light brown saddle from base of posteriormost dorsal
fin ray to caudal peduncle. Aquarium
Care: An aquarium having a gravel substrate
and containing areas of pebbles, small rocks and a
scattering of small grass like plants would make an
ideal set up for these little hillstream catfishes.
Fish such as Brachydanio rosaeus and Barbus
rhombocellatus would make excellent tank companions
for these small, but somewhat inconspicuous members
of the Akysidae family.Diet:
A diet of live foods
such as: Daphnia, Cyclops, small bloodworms and white
worms should be offered, as like most of the sub-family
‘Parakysinae’, Parakysis notialis
tends not to feed upon commercially prepared dried
foods; although they will accept small frozen bloodworms.
Etymology:
The genus name Parakysis: para-, near, i.e.,
similar to Akysis but lacking an adipose
fin. The specific name notialis: From
the Greek notos, meaning southern, in reference to
the distribution of this species (southern Borneo).
