rosie does your lfs
only stock male rosy barbs, they do better when they are in pairs.
They are nothing like tiger barbs in there temperament, they are far more placid and they like the company of females. they are still like other fish and like to be in groups, but they really like mixed groups and that way they will really show there colours.
To sex them firstly, the fins of the male are pink and the tips of the dorsal are black. In the female the fins are almost colorless. I have also found that the males are sometimes more golden in colour were as the female is more yellowish.
