Care guide
Species care notes
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 70–82 °F, pH 5.5–7.5, 1–10 dGH.
- Behaviour: temperament peaceful; a shoaling fish best kept in a group of six or more; suited to a community tank.
- Difficulty: Beginner (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.”
- Breeding: “Once sexually mature this species can be stimulated to spawn by performing cool water change, and apparently displays a preference to deposit its eggs on submerged leaf litter.”

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), pH 6–8, hardness 2–25 dH. |

What this means for care
- Keep water within its wild range, 72–79 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 91°F (up to 91°F in the hottest sampled areas) |
| Cool-season lows | about 70°F (down to 70°F in the coldest sampled areas) |
| Average temperature | 79–79°F across sampled records |
| Relative humidity | 78–79% on average (driest month about 72%) |
| Rainfall | about 2297 mm a year |
Measured at 5 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.
