How do you calm angelfish down?

You can calm angelfish down by:

  • Not overcrowding the tank
  • Maintaining good tank conditions
  • Not disturbing their tank too often
  • Providing them with enough food
  • Providing them with plenty of plants and decoration to interact with
  • Giving them 6 to 8 hours of darkness to rest
  • Separating those that are particularly aggressive
  • Separating breeding fish as they are prone to stress and aggression

Take action immediately as soon as your angelfish start exhibiting aggression. You’ll notice them fin-nipping, lip-locking, chasing other fish around the tank, or other similarly erratic behaviors.
