Do oscar fish like mirrors?

Yes, oscar fish like mirrors. Oscar fish have a competitive and dominant nature. When they face a mirror, they might mistake their reflection for another fish and try to fight it. Providing your oscar fish with a small floating mirror can reduce their boredom and encourage them to stay active.

However, you shouldn’t leave the mirror in the tank for more than 5-10 minutes at a time. Otherwise, your oscar fish might get tired and even injure itself after fighting its own reflections for too long.

Aside from mirrors, you can also provide other toys to entertain your oscar fish, such as:

  • Ping pong balls
  • Floating tubes
  • Waterwheels
  • Fishing bobbers
  • Moss balls
