can mirror back stress fish?

  • We are currently upgrading MFK. thanks! -neo
If yes > should I buy new tank or is there a way to cover it up?

Mirrors are used to stimulate the nuchal humps on flowerhorns and other large cichlids..........The fish fight their own reflection, which in return stimulates their forehead to grow(so the saying goes).............
