I do not think that tiger barbs are aggressive. They are really just curious. Put them in a large tank and they will not bother anybody. Any comments?

It depends on the numbers, cer. A pair can be a disaster, and numbers under six is a crapshoot. I always recommend at least eight for total peace.

I guess in a proper school size in the right size tank of say 150 gallons long, with a great amount of planting with appropriate tank mates of the same region you would have a great peaceful tank with the occasional out burst.
