Danio breeding habits?

[lime_smash]

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!

Yes, they'll all breed with each other- most crosses between different kinds look like regular zebra danios.

They're all the same species- or in the leopard's case a subspecies. They'll mate readily but you might not even know it- they eat their own eggs. They scatter them on the floor and they and their tank mates soon eat them... hey, no-one called them smart!

I think I read if you want to breed them your best putting them in above marbles so they can't get to the eggs.

zebra danios will breed very readily in aquairums, given they have plenty of food and a few other factors

Incidentally, I have seen a photo of a Danio that looked like a washed out GloFish with black stripes.

Obviously a Danio/Glofish cross... I don't know if it was F1 or F2, or if it is possible to get that outcome with the first gen or if the first gen all look like Zebs.

I think a partial water change as well as slightly raised temp due to the warm weather was partially responsible. They have returned to perfectly normal behavior today so I guess I'll just have to wait and see. I'm sure if they did the cories in the tank have probably had a feast by now.
