Males are more streamlined than the deep-bodied females and sometimes the males have a golden background color as opposed to the females' silver. In long-finned varieties, the males have longer fins than the females. This isn't as evident in the normal wild-type fish which all have short fins.
The Wolf has a site about danios with a pic of a male and female zebra danio to illustrate the differences.
I have 4 stripy ones and ones kinda dotty and i thought maybe that one was feamle. I think they are male though but this one looks different to the rest.
no, just leopards and zebras. male danios are long and slender, like torpedoes. female danios have got a massive pot-belly on them and look like they've swallowed a dime.
I have four stripy ones and a dotty one too. But from the way you are talking about thier bellies the dotty one is def female, i thought she was looking a little fat.
