Those look nice. How big do they get?
Their max adult size is one of their best attributes, they only go to about 6-9", so they're well within the range for many of us mini monster guys. They're best kept in groups of around half a dozen so a 180g seems reasonable to me.
They belong to the cyprinid family and come from the far east, but don't have any barbels, hence beardless barb. The only detail I can't seem to find anywhere is life span and although they're meant to be peaceful they might be fin nippers for all I know and it'd be nice to know how they get on with plants, just a few details that I thought someone would be able to fill in.
But sadly, although a few members like these fish, going off reactions, it seems that no one has kept them
