SOUTH AMERICA: Paraguay River basin, Mato Grosso,
Min Tank Size:
15 gallons (60 liters) or larger.
Min Shoal Size:
Best in groups of six or more.
OMNIVORE: Enjoys a varied diet of live and frozen
bloodworm, blackworm, brine shrimp, daphnia, grindal worm, tubifex
and white worm complimented with algae tablets and catfish pellets
and tablets and granules designed for bottom feeding catfish.
Temperature of 72 to 82°F (22 to 28°C),
pH 6 to 8.0, 2-25° dH
Moderate to Easy. To replicate an Amazon biotope,
begin by adding a substrate soft river sand. A few dried leaves
can be scattered on the surface of the substrate to help create
mildly tanic water. Add pieces of driftwood, dried branches stripped
of bark or roots for cover. Plants can be added around the sides
of the tank and the center of the tank left open for swimming.
Dim lighting is preferred. Water should be extremely clean, well-oxygenated
and have a mild current.
Extremely gentle, peaceful fish that
do well as part of a species-only or a community tank. Best kept
as part of a shoal of 6 or more, with a ratio of 2 males to 3
females. Excellent community tankmates include: anabantoids, cardinal
tetras, small characins, cyprinids, dwarf cichlids, danios, guppies,
mollies, platys, swords, otos, small plecos and other small catfish.
Indigenously, the characin Astyanax bimaculatus (Twospot axtyanax)
follows C. polystictus to eat the algae, crustaceans, insects
and plant matter exposed by this catfish's substrate sifting.
Good for all – Some experience required.
olystictus: Gk. “Poly” meaning “many” and “stictus”
meaning spotted. The estimated lifespan for C. polystictus is
2 – 5 years.
