Danio chasing others

[Mrfishypants]

Help Why is one of my zeb danios chasing the others relentlessly ?????

 

[BillD]

He (?) is probably the dominant fish and that is what they do. Perhaps he wishes to breed. Nothing to worry about, although you could get a few more to spread out the aggression.

Tank size could also be a factor.. zebra danios need some room to swim. They're definitely active little fish.
