How to make it work
- Add the calmer, smaller fish first, and the tiger barb 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.
