Tiger barbs fighting

[New Boy]

I had 6 tiger barbs until recently who hung around constantly together and didn't fight much. To make them happier I added 3 small golden/albino tiger barbs. Unfortunately this seems to have had the opposite effect and the small albino tigers chase the (twice their size) normal stripped tigers all over the place (constantly). Anything I can do about this? I expected them all to shoal together, any ideas why they haven't?

Cheers

You've disrupted their already established pecking order. Now they are starting all over again.

Yeah, that very well could be. Is it causing damage or really weakening your big guys?

They will probably settle down after a while. This isn't exactly the same, but when I added a pristella tetra to make my already adjusted 2 pristellas happier, it disrupted their "shoaling". They used to swim together almost all the time, but the new guy changed things. Nearly a month later, all 3 are swimming together fairly often.

However you could have some added stress and fin nips until this happens. Albinos are not always treated like the other fish, and sometimes they don't get along the same.
