For the last few days, one of them has been pestering the others. I don't know if they are playing around, mating, fighting, or what. It looks like they are trying to push each other out of their way. It seems like there is only one instigating it all. This fish has "whiskers" that appear to point down from the corners of its mouth, too. I didn't know danios had them.
One more question, are danios livebearers?
