The caudal fin is somewhat variable, usually scalloped
with rounded (or at least not very sharp) lobes, the
upper one the larger. Colouration:
Dark brown markings on a light brown background. The
pale band across the nape is irregular, running zigzag
and in a few specimens it is actually interrupted,
the dark area on the head and predorsal region being
in contact across it. The dark area below the dorsal
fin is a peculiar four cornered shape when the fish
is viewed from above. A dark area on the adipose fin
and just below, with a light patch at the origin of
the adipose fin. The dark band across the caudal peduncle
is always more or less triangular in shape. The dark
markings on the body are enhanced by the fact that
just around them the background is paler than elsewhere
on the body, almost white instead of light brown.
Dorsal fin with a dark bar about one third halfway
up, caudal fin with a dark vertical bar about one
third from end, all the fins are minutely spotted.
Habitat: Occurs in forest creeks
with little current; living on the bottom which is
covered with decaying leaves. Aquarium Care:
Hiding places such as rockwork, plants and or wood
will benefit this species and help, along with regular
water changes, to keep it happy in its surroundings.
A good addition to the medium sized community tank,
and will not harm the occupants unless they are small
enough to fit into its mouth such as newly born fry
and young fish. If you keep livebearers such as Guppies
and Platies in with them you will very rarely be overrun
with fry as the Dwarf marbled catfish will promptly
finish them off on its night time prowls. Diet:
Can be fed a varied diet of tablet food, pellets,
worm foods and frozen food such as bloodworm.
