AngelfishPterophyllum scalare
Oscar CichlidAstronotus ocellatus
Verdict:not recommended
- Behaviour: not recommended
- Water: the shared range is very narrow
Why
The oscar is a predator up to 35 cm, twice as large as the angelfish, and needs a tank of at least 500 l. The shared temperature is only a narrow band of 24–25 °C, so keeping them together is not recommended.
Water and size
| Parameter | Angelfish | Oscar Cichlid | Shared range |
|---|---|---|---|
| Temperature | 24 – 28 °C (75 – 82 °F) | 22 – 25 °C (72 – 77 °F) | 24 – 25 °C (75 – 77 °F) the shared range is very narrow |
| Water pH | 6 – 7 | 6 – 8 | 6 – 7 ranges overlap |
| Water dH | 5 – 10 | 5 – 19 | 5 – 10 ranges overlap |
| Size in aquarium | 15 cm (5.9 in) | 35 cm (14 in) | |
| Required aquarium volume | from 200 L (53 gal) | from 500 L (132 gal) | |
| Keeping | Schooling (usually from 5–6 individuals and more) | Pair (male/female) | |
| Temperament | Semi-peaceful (dangerous to smaller ones) | Predator, but semi-peaceful (gets along with large ones) | |
| 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.
