I read somewhere that when the rosy barbs are tryig to breed, the male will chase the female and try to push her into things like plants to squeeze eggs out, this is why they suggest having lots of plants in the breeding tank. i was watching my tank today and my male appears to be bullying the female, could this be breeding behavior, he is chasing her in very tight circles. i have a power filter, and it is a community tank, with a fair number of bottom feeders, so i do not anticipate that any fry will hatch even if this is what is happening.
