Had a tiger barb tank 55g for about two years, these little guys are crazy! They look good and move around in a group which is fun to watch, little or no pecking but they are super hyper, like a kid after overdosing on sweets. Forget tank mates, they are super-fast aggressive feeders, the only fish I tried that made a good mix and could compete for food were Buenos Aires tetras which are also fast feeders. So if you like lots of action no aggression, these guys can work and the more, the better.
