Bronze CorydorasCorydoras aeneus
Verdict:compatible
- Behaviour: compatible
- Water: ranges overlap
Why
Both species are peaceful, and they use different layers. The water matches: pH 7–8, hardness 15–18 dGH, although this is the upper end of the range for a corydoras. Overall these two fish are compatible.
Water and size
| Parameter | Black Molly | Bronze Corydoras | Shared range |
|---|---|---|---|
| Temperature | 21 – 26 °C (70 – 79 °F) | 21 – 27 °C (70 – 81 °F) | 21 – 26 °C (70 – 79 °F) ranges overlap |
| Water pH | 7 – 8.5 | 6 – 8 | 7 – 8 ranges overlap |
| Water dH | 15 – 30 | 5 – 18 | 15 – 18 ranges overlap |
| Size in aquarium | 8 – 12 cm (3.1 – 4.7 in) | 7 cm (2.8 in) | |
| Required aquarium volume | from 150 L (40 gal) | from 70 L (18 gal) | |
| Keeping | Mixed (solitary / pair / group) | Small group (5–6 individuals) | |
| Temperament | Peaceful (regular) | Peaceful (regular) | |
| Swimming level | near the surface | near the bottom |
This is a general estimate: fish of the same species differ in character. Tank volume is given for each species separately — two species together need at least the larger of the two, and usually more.
