Oscar CichlidAstronotus ocellatus
Verdict:not recommended
- Behaviour: not recommended
- Water: ranges overlap
Why
The oscar is a predator up to 35 cm: it eats fish much smaller than itself. A platy is only 5–7 cm, so for the oscar it is prey, and they should not be kept together.
Water and size
| Parameter | Common Platy | Oscar Cichlid | Shared range |
|---|---|---|---|
| Temperature | 20 – 28 °C (68 – 82 °F) | 22 – 25 °C (72 – 77 °F) | 22 – 25 °C (72 – 77 °F) ranges overlap |
| Water pH | 7 – 8.2 | 6 – 8 | 7 – 8 ranges overlap |
| Water dH | 10 – 30 | 5 – 19 | 10 – 19 ranges overlap |
| Size in aquarium | 5 – 7 cm (2 – 2.8 in) | 35 cm (14 in) | |
| Required aquarium volume | from 60 L (16 gal) | from 500 L (132 gal) | |
| Keeping | Mixed (solitary / pair / group) | Pair (male/female) | |
| Temperament | Peaceful (regular) | Predator, but semi-peaceful (gets along with large ones) | |
| 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.
