No, angelfish can’t live with oscars. Both angelfish and oscar fish have territorial and aggressive tendencies, so keeping them in the same tank will result in conflict.
Moreover, oscars are significantly bigger than angelfish and are seen as the more aggressive fish between the two. The brutish and fast-swimming oscars might see the smaller and slower angelfish as intruders and attack them. This dynamic might eventually stress out both the angelfish and the oscars.
Instead, try housing your oscars with laid-back fish that will stay out of their way but are still able to hold their own against aggression.
Here are some excellent examples of suitable oscar fish tank mates:
- Convict cichlids
- Severum cichlids
- Firemouth cichlids
- Jewel cichlids
- Silver dollars
- Red tail sharks
- Clown loaches
