Pseudoplatystoma fasciatum (common names barred sorubim or barred catfish) is a species of long-whiskered catfish native to Brazil.
Care at a glance
Species-specific aquarium care
- Tank: An adult reaches about 41.1 in (104.5 cm). That needs a pond or public-aquarium-scale system, far beyond a home aquarium.
- Water: Freshwater.
- Temperature: 75–82°F (range recorded for this species).
- pH: 6–8.
- Hardness: 4–30 dGH.
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- Diet: A predator: feed meaty foods sized to its mouth (frozen fish, shrimp, worms); it will eat tankmates that fit in its mouth. FishBase classes it as a carnivore.
- Availability: Mostly kept by public aquariums; private keeping is uncommon.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–79 °F, pH 6–7.6, 2–30 dGH.
- Behaviour: temperament peaceful.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Strictly speaking, decor isn't necessary for a tank containing an adult, provided the lighting is fairly dim.”
- Diet: “Piscivorous by nature, but usually adapts well to dead foods in captivity.”
- Tankmates: “Whilst it won't hesitate to gobble any smaller fish, it's actually quite peaceful and can be kept alongside other similarly-sized species in suitable surroundings.”

Long-whiskered catfish
Applies to most species in this group. Habitat: South American pimelodids occupy river channels and tributaries, with redtails and shovelnoses also using flooded forests. [fg178-pictus, fg178-redtail, fg178-sorubim]. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- For P. pictus, use at least 120 × 45 × 45 cm (about 243 L), with open swimming space.
- Adult redtails and P. fasciatum require facility-scale housing: approximately 360 × 240 × 120 cm (10,368 L) is explicitly only a minimum in the reference.
- Provide dim lighting and appropriately sized shelters; use fine sand for pictus.
- For giant species, secure heavy furnishings and avoid swallowable gravel; bare bottoms or large smooth pebbles are alternatives.
- Use efficient biological filtration, regular partial water changes and, for giants, equipment protected in an external sump.
Climate & lighting
| Water | 71.6–77°F |
Diet
- Pictus: sinking prepared foods and frozen bloodworms.
- Earthworms, sized for the fish.
- Giant predators: prawns and mussels.
- Giant predators: white-fish portions; vary foods and reduce feeding frequency as adults mature.
Social life
- Pictus are shoaling fish, preferably six or more in adequate space; adult redtails and shovelnoses can be territorial towards other large pimelodids. Companions must be too large to swallow.
Health watch
- Barbel erosion with deteriorating water quality.
- White spot and poor condition in newly imported pictus.
- Obesity and fatty organ damage from overfeeding or inappropriate mammal meat.
Understanding the animal
About this animal
About this animal
It inhabits freshwater systems within the Guiana Shield and utilizes both rivers and wetlands as habitat. P. fasciatum have distinct vertical bars across the body, and females are larger in size compared to males.

In the wild
In the wild
From this species’ own FishBase record (habitat, bottom type, water and breeding data), not its family. Good care copies these conditions.1
| Where it lives | Lives in freshwater, in rivers and streams, lakes. Stays near the bottom. Occurs throughout the principal riverbeds and sometimes in the flooded areas of forests. Its biology is similar to that of P. tigrinum but it appears to be more fond of shady streams. Feeds at night on fish (loricariids, cichlids and characoids) as well as crabs. |
| Water it lives in | Freshwater, 75–82 °F (24–28 °C), pH 6–8, hardness 4–30 dH. |
| Climate | Tropical climate. |
| Wild diet | Hunting macrofauna (predator). |
What this means for care
- Keep water within its wild range, 75–82 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 91°F (up to 93°F in the hottest sampled areas) |
| Cool-season lows | about 69°F (down to 58°F in the coldest sampled areas) |
| Average temperature | 76–81°F across sampled records |
| Relative humidity | 75–83% on average (driest month about 72%) |
| Rainfall | about 2038 mm a year |
Measured at 267 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

| Overview | Pseudoplatystoma fasciatum (common names barred sorubim or barred catfish) is a species of long-whiskered catfish native to Brazil. It inhabits freshwater systems within the Guiana Shield and utilizes both rivers and wetlands as habitat. P. fasciatum have distinct vertical bars across the body, and females are larger in size compared to males. Pseudoplatystoma species are adapted to hydrologic variation, reproducing during highflow events. — Wikipedia (community-edited) |
| Where it lives | Home ranges Population dynamics Growth parameters Max. ages / sizes Length-weight rel. Length-frequencies Mass conversion Recruitment Abundance Life cycle Reproduction Maturity Maturity/Gills rel. — FishBase |
| Wild diet | P. fasciatum primarily feeds on fish and small crabs, including anostomids, loricariids, cichlids, and crabs. Like other Pseudoplatystoma species they can be found feeding at night near the benthos. Feeding in low light can be difficult to find prey if the species is not equipped with the right tools. — Wikipedia (community-edited) |
| Appearance and size | Maximum length 105 cm sl male/unsexed; maximum published weight 70.0 kg. — FishBase |
| Biology | Adults occur throughout the principal riverbeds and sometimes in the flooded areas of forests. Their biology is similar to that of P. tigrinum but appear to be more fond of shady streams. They feed at night on fish (loricariids, cichlids and characoids) as well as crabs. — FishBase |
| History and naming | The etymology of Pseudoplatystoma fasciatum comes from Greek and Latin roots. The genus name is pseudo meaning false, platys meaning flat, and stoma meaning mouth. — Wikipedia (community-edited) |
| Conservation | As of their last assessment in 2021, P. fasciatum is categorized as least concern by the IUCN. However, like many species of freshwater fish worldwide, their population is decreasing in size and becoming increasingly fragmented. Hydroelectric dams are a major threat to Pseudoplatystoma species, who rely on seasonal flood pulses for migration and reproduction. — Wikipedia (community-edited) |
