Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 2.6 in / 6.51 cm).
- Water: Freshwater.
- Temperature: 70–75°F (range recorded for this species).
- pH: 6–8.
- Hardness: 2–25 dGH.
- 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 47 × 18 in (roughly 64 US gallons); space needed is rated “large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–82 °F, pH 5–7.5, 2–12 dGH.
- Behaviour: temperament peaceful; a shoaling fish best kept in a group of six or more; not a community fish.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Ideally use a substrate of fine sand, although rounded gravel is an acceptable alternative provided that it is kept scrupulously clean.”
- Tankmates: “Peaceful with the majority of other fishes, but males in particular can be aggressive towards conspecifics and other similarly-shaped species.”
- Breeding: “Can be bred in a similar fashion to many other Corydoras species, although it may be preferable to use pairs of adults rather than a mixed group in order to minimise aggression.”

| Where it lives | Lives in freshwater. Stays near the bottom. |
| Water it lives in | Freshwater, 70–75 °F (21–24 °C), pH 6–8, hardness 2–25 dH. |
| Climate | Tropical climate. |
What this means for care
- Keep water within its wild range, 70–75 °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 69°F (down to 63°F in the coldest sampled areas) |
| Average temperature | 78–79°F across sampled records |
| Relative humidity | 82–84% on average (driest month about 81%) |
| Rainfall | about 2863 mm a year, spread fairly evenly |
Measured at 6 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.
