We have 6 zebra danios but they seem to be fighting and bullying ?
Any advice please?

How big is the tank? A tank size of at least 10 gallons is recommended for zebra danios so they have enough swimming space.
You can try adding plants or decorations to block their line of sight.
If you followed those rules, then I wouldn't worry about it too much as long as they are not tearing each others fins.
