Why
Male guppies have bright colours and long tails. A male Siamese fighting fish takes such fish for rivals and attacks them, so keeping these fish together is not recommended.
Water and size
| Parameter | Siamese Fighting Fish | Common Guppy | Shared range |
|---|---|---|---|
| Temperature | 22 – 28 °C (72 – 82 °F) | 17 – 28 °C (63 – 82 °F) | 22 – 28 °C (72 – 82 °F) ranges overlap |
| Water pH | 6 – 8 | 7 – 8.5 | 7 – 8 ranges overlap |
| Water dH | 5 – 19 | 10 – 30 | 10 – 19 ranges overlap |
| Size in aquarium | 7 cm (2.8 in) | 3 – 6 cm (1.2 – 2.4 in) | |
| Required aquarium volume | from 40 L (11 gal) | from 40 L (11 gal) | |
| Keeping | Solitary | Mixed (solitary / pair / group) | |
| Temperament | Territorial (often aggressive) | Peaceful (regular) | |
| Swimming level | near the surface | near the surface |
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.
