Care at a glance
Species-specific aquarium care
- Tank: At least 96 in long and 48 in front to back for one adult (adults commonly reach about 23.6 in / 60 cm).
- Water: Freshwater.
- Temperature: 72–79°F (range recorded for this species).
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.
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
- Tank: a base of at least 394 × 157 in (roughly 42272 US gallons); space needed is rated “very large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–90 °F, pH 6–7.6, 1–12 dGH.
- Behaviour: kept alone; not a community fish.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “The choice of décor is as much down to personal preference as anything else though a carefully-aquascaped, planted set-up is obviously out of the question.”
- Diet: “Almost entirely piscivorous preying on smaller fishes captured in the water column in nature, though most specimens readily adapt to dead alternatives such as prawn/shrimp, mussel, squid, whitebait, strips of larger white fish, etc., in aquaria.”
- Tankmates: “Only keep with species large enough to avoid predation and that require similar environmental conditions.”

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.

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. Stays near the bottom. |
| Water it lives in | Freshwater, 72–79 °F (22–26 °C). |
| Climate | Tropical climate. |
What this means for care
- Keep water within its wild range, 72–79 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 89°F (up to 92°F in the hottest sampled areas) |
| Cool-season lows | about 66°F (down to 63°F in the coldest sampled areas) |
| Average temperature | 76–80°F across sampled records |
| Relative humidity | 81–85% on average (driest month about 78%) |
| Rainfall | about 2228 mm a year |
Measured at 25 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.
