Can Platies and Zebra Danios Live Together?

Yes, usually. Platies and zebra danios like the same water: 68–77 °F (20–25 °C) and a pH of 7–8. Platies spend their time in the middle and zebra danios near the top, so they stay out of each other's way.

How to make it work

  • Add the calmer, smaller fish first, and the larger fish last.
  • Use plants, wood or rocks to break up the view across the tank. Fish that cannot see each other all day fight less.
  • Watch closely for the first week. Torn fins, hiding or a fish that stops eating mean it is not working.
  • Keep a spare tank or a divider ready, so you can separate them the same day.
