Common GuppyPoecilia reticulata
Neon TetraParacheirodon innesi
Verdict:with caution
- Behaviour: compatible
- Water: the shared range is very narrow
Why
Both fish are peaceful and small, and they do not bother each other. The difficulty is the water: neon tetras need soft, acidic water, guppies hard, alkaline water. There is only one shared point: pH 7 and hardness 10 dGH.
Water and size
| Parameter | Common Guppy | Neon Tetra | Shared range |
|---|---|---|---|
| Temperature | 17 – 28 °C (63 – 82 °F) | 20 – 25 °C (68 – 77 °F) | 20 – 25 °C (68 – 77 °F) ranges overlap |
| Water pH | 7 – 8.5 | 5 – 7 | 7 the shared range is very narrow |
| Water dH | 10 – 30 | 1 – 10 | 10 the shared range is very narrow |
| Size in aquarium | 3 – 6 cm (1.2 – 2.4 in) | 4 cm (1.6 in) | |
| Required aquarium volume | from 40 L (11 gal) | from 54 L (14 gal) | |
| Keeping | Mixed (solitary / pair / group) | Schooling (usually from 5–6 individuals and more) | |
| Temperament | Peaceful (regular) | Peaceful (regular) | |
| Swimming level | near the surface | 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.
