GoldfishCarassius auratus
Neon TetraParacheirodon innesi
Verdict:not recommended
- Behaviour: not recommended
- Water: ranges overlap
Why
A goldfish is dangerous for noticeably smaller tankmates, and a neon tetra is only 4 cm. On top of that, the shared temperature is only a narrow band of 20–22 °C, so keeping them together is not recommended.
Water and size
| Parameter | Goldfish | Neon Tetra | Shared range |
|---|---|---|---|
| Temperature | 18 – 22 °C (64 – 72 °F) | 20 – 25 °C (68 – 77 °F) | 20 – 22 °C (68 – 72 °F) ranges overlap |
| Water pH | 6 – 8 | 5 – 7 | 6 – 7 ranges overlap |
| Water dH | 5 – 19 | 1 – 10 | 5 – 10 ranges overlap |
| Size in aquarium | 10 – 30 cm (3.9 – 12 in) | 4 cm (1.6 in) | |
| Required aquarium volume | from 300 L (79 gal) | from 54 L (14 gal) | |
| Keeping | Schooling (usually from 5–6 individuals and more) | Schooling (usually from 5–6 individuals and more) | |
| Temperament | Semi-peaceful (dangerous to smaller ones) | Peaceful (regular) | |
| Swimming level | middle level | middle level |
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.
