    Zebra Danio - sexually active?

    Hi All,

    I bought some Zebra Danio (hopefully i get the right species). And the 8 of them seem to be very active sexually, even more compared to guppies and from what i read in this article, "Zebra danios normally spawn with just one partner. " But they seem to be engaged in kind of "group party" and so, i am not exactly confident that i got the right species... cost about S$0.80 per piece.

    Would appreciate your inputs. Thanks!

    Danio rerio is not a characin!
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    yep... danios are very sexually active.

    make sure you get 1 male(slim shape) to 2 females(more round shape). kind of hard to tell if both are underfed in lfs.

    Get it wrong...you will get orgies 3-4 males chasing 1 female.

    (Edit: Please kindly refrain from using SMS language in the forum, e.g. 'u', thanks!)

    Re: Zebra Danio - sexually active?

    Some males are a little yellow compared to the females. Also smaller but this assumes the whole lot was bought as a batch.

    Put in a bunch of smooth pebbles at the edge of the glass. If the females spawn, the eggs will fall through the gaps and won't be eaten. If you catch them spawning, the males will be chasing after the females. The females will just scatter a lot of eggs. They are transparent so you will have to look carefully. The males follow and presumably fertilise the eggs but I have not been able to spot any difference. Many of the eggs will be eaten.

    Look carefully after a few days and you might see the fries clinging onto the glass, especially in the gaps of the pebbles. They are very tiny like the comma above. If you have a turkey baster, you can suck them out and grow them out separately from the adults.

    They spawn frequently. You should have more females than males.

    You can say that they're mostly tank-raised Brian. I don't think anyone still imports wild-caught Zebra Danios, except for the new ones from Myanmar and India.

    Wild collection is very limited timebeing . Also market request reduced too much if you compare 80's and 90's . Mostly local breeders supply to the market . I know still there are 3 breeders at LA.

    Re: Zebra Danio - sexually active?

    JJ,

    Hehe. Probably more than that! No, I was just thinking about how when I was a child (196 my father showed me the glass marble idea and we bred thousands of these fish. Without regular collections over the intervening 40 years, I would tink they might start to show signs of in-breeding. How do the wild caught ones differ in appearance from there aquarium counterparts? Where is the type locality for B. rerio?

    Best wishes from sunny Portland, Oregon where to-days high temperature will be -1C with a low of -10C..................

    it is much more economical to raise them breeding. an indian exporter that I know will do wild collection by request.
