  • Keep an eye on body language: Pay close attention to the fish’s body language. Raised fins, flaring gills, or darkening colors can indicate aggression. If you observe these behaviors, take necessary steps to diffuse the situation, such as adding more hiding spots or rearranging tank decor.
  • Separate aggressive individuals: If one fish is excessively aggressive and causing harm to others, it may be necessary to separate them. Providing individual tanks or utilizing temporary partitions in the tank can help prevent further aggression.
  • Consider tank size: A larger tank with ample swimming space and hiding spots can reduce aggression. With more space, each fish will feel less threatened by the presence of others.
  • Adjust tank mates if needed: If aggression levels remain high despite efforts to manage it, consider rearranging tank mates. Some species of Cichlids may be more compatible with Oscars than others. Prior research and expert consultation can help find suitable tank mates.
