Tiger Barb & Green Tiger Barb Behavior

[Dandee]

I have only had these Tiger Barbs & Green Tiger Barbs (a school of 5) for a couple weeks. I have not seen them do this before. I caught this behavior last night and I'm not sure if they are fighting, playing, arguing, or what. They did this for about 1/2 an hour last night and have not done it again. Anyone have some ideas?

I have 5 Tiger and 4 Green.
My Tigers do this occasionally - it's a dominance thing - I think.
I see more of this just before an egg laying session by the female(s).
As long as the school is big enough you should not see a lot of this.

Thanks. They have only done that the once that I have seen.

Normal behavior. Tiger barbs are also known for going "tail-up" often and a lot of other weird rituals related to breeding.
