Tiger Barbs are not aggressive fish. Never have been. There’s only ever two reasons why Tiger Barbs become aggressive. Not enough of them, and not enough space.
Ive had them a few times over the years, and I can recommend them as IDEAL community fish. Put 20 in a 6ft tank and you get a peaceful, playful group that keeps itself to itself. They never bother other fish and never stop moving.
They need space. They’re very active, like a group of kids running round. If they don’t have the space... if other fish are too close theyre in the way, so they’ll get nipped and chased.
They’re also very social, with a pecking order, so too few also leads to aggression, which will spill over towards other fish.
Kept properly, say 10 or 20 (or more) in a big tank, Tiger Barbs are excellent community fish. If you don’t believe, try it and see.
