Can anyone tell me a bit about the breeding habits of zebra danios. I have several in a tank a recently I had two (what I believe to be) males harassing a rather round "female". Not sure about sexing since they are the gold ones just basing it on the body shape. I have several questions. Do danios breed readily in aquariums? Where do they lay their eggs? Will a zebra danio breed with a glo-fish or a leopard danio and if so should they not be allowed to breed with each other? Any other genreral info would be great!
