thats good to know. I think I have a breeing pair already. Out of my 10 tiger barbs, 3 of them are adult size. Of thoes 3 adults, 2 are female and one is male. I've noticed the male chases one of the femaled constantly. The female alwayse looks like shes trying to loose the male, but he is too persistant. At fist I thought that he was trying to kill her, but maybe hes just trying to mate?
the best way to sexy tiger barbs, IMO, is to look at there size, shape, collour and behavior.
Females tend to be bigger and more rounded, maled tend to be flater in shape and a bit smaller. Females also tend to be less collourfull with only a slight redish tinge on the nose. Males uasily have a more pronounced red spot on there nose.
