Fish with passive temperaments can live with oscars. Oscar fish have feisty temperaments, so you should house them with laid-back fish that won’t get in the oscars’ way or provoke their aggressiveness.
With that said, the oscar fish tank mates should still be able to hold their own against aggressions, in case the oscars decide to assert their dominance. Moreover, you should choose fish that are quite large. Oscars are opportunistic feeders, so they might devour any fish small enough to fit in their mouths.
Here are some great fish that can live peacefully with oscars:
- Convict cichlids
- Severum cichlids
- Firemouth cichlids
- Jewel cichlids
- Arowanas
- Silver dollars
- Red tail sharks
- Plecostomus
- Clown loaches
