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 1.7 in / 4.32 cm).
- Water: Freshwater.
- Temperature: 72–77°F (range recorded for this species).
- pH: 6–7.2.
- Hardness: 8–12 dGH.
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
- 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 24 × 12 in (roughly 14 US gallons); space needed is rated “modest tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–77 °F, pH 6–7.5, 2–12 dGH.
- Behaviour: temperament peaceful; a shoaling fish best kept in a group of six or more; suited to a community tank.
- 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 it's kept scrupulously clean.”

Understanding the animal
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. Uses both the bottom and open water. |
| Water it lives in | Freshwater, 72–77 °F (22–25 °C), pH 6–7.2, hardness 8–12 dH. |
| Climate | Tropical climate. |
What this means for care
- Keep water within its wild range, 72–77 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 88°F (up to 92°F in the hottest sampled areas) |
| Cool-season lows | about 62°F (down to 59°F in the coldest sampled areas) |
| Average temperature | 71–79°F across sampled records |
| Relative humidity | 70–74% on average (driest month about 67%) |
| Rainfall | about 1276 mm a year, with strong wet and dry seasons |
Measured at 10 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.

Each bar is what one source reports. Where several sources weigh in, the dashed gold band marks their average.
Adult length
Maximum recorded length. Measured as standard length (snout to the base of the tail, not counting the tail fin). Fish in home aquariums often stay smaller than wild records.
Water temperature
Range the species tolerates in nature; aim for the middle.
Minimum tank footprint
Seriously Fish recommends a tank base of at least 24 × 12 in (about 14 US gallons).
