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 1.6 in / 4 cm).
- Water: Freshwater.
- Temperature: 66–70°F (range recorded for this species).
- pH: 6.5–7.2.
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
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.

African killifish
Applies to most species in this group. Habitat: African killifish occupy permanent small streams and swamps as well as seasonal floodplain pools that dry out, where annual Nothobranchius survive as eggs. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- For an Aphyosemion australe pair or trio, provide at least a 45 × 25 cm (18 × 10 in) footprint; a Nothobranchius rachovii pair needs at least 45 × 30 cm (18 × 12 in).
- Fit a tightly sealed cover: lyretails are accomplished jumpers.
- Provide floating vegetation to shade the water and plants or spawning mops; Epiplatys use surface vegetation for egg laying.
- Use gentle aeration or filtration; maintain clean water and separate breeding species and locality strains.
- Collect annual N. rachovii eggs in spawning medium for separate incubation; its profile specifies 5–7 months of storage before wetting.
Climate & lighting
| Water | 70–75°F |
Diet
- Live or frozen Daphnia and Artemia.
- Chopped bloodworms and appropriately sized worms.
- Small insects for surface-feeding Epiplatys; tiny live foods for small fry.
Social life
- A. australe can be kept as a pair or trio with carefully selected peaceful companions; breeding tanks should hold one species and locality strain.
Health watch
- Velvet susceptibility in A. australe fry.
- Fungal loss of incubating eggs.
- Nutritional deficiencies from an unsuitable diet.
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. Not a seasonal killifish. Is easy to maintain in the aquarium. |
| Water it lives in | Freshwater, 66–70 °F (19–21 °C), pH 6.5–7.2. |
| Climate | Tropical climate. |
What this means for care
- Keep water within its wild range, 66–70 °F.
