I have leopards and red glow lights in my tank. They breed all the time. When I have them in my 29g some of the fry survive. They are so pretty. It's a neat thing. I don't have any regulars zebra danios but I have looked at some of the dominant vs recessive traits. I know that zebra stripe, long finned, red is dominant. I don't know about the other colors because I only bought the red ones. I think to get a leopard I would have to have a leopard red with is VERY hard to find. Then you'd probably only get one in a blue moon even so as stripe is dominant. It would be interesting.

Tex Gal you should find that your offspring Danios are already carrying the 'spotted gene'. They will probably be heterozygous carriers if the striped gene is dominant.
As you crossed SS (homozygous Striped fish) with ss (Homozygous Spotted fish each will have got one copy from each parent so they should all be Ss, heterozygous fish, carrying the dominant striped gene so looking stripy, but carrying the spotted gene too.
If you cross two of these with each other 25% should be spotted, while 50% will be heterozygous carriers like their parents and 25% will be homozygous striped fish. Obviously the last two groups will all look the same stripy fish.
I'm not sure whether the other factors are simple dominant and recessive genes (in fact I'm pretty sure I remember reading somewhere that transgenic genes often don't behave like this) but if they are then the same ratios will apply to them too.
Obviously two unrelated genes it'll mean only a quarter of the 25% spotted fish will have the other recessive character, and only a quarter of those will have the third recessive feature and so on...
That would mean for three independant recessive characters you would only get an average of 1.5625 fish out of 100 would show all three recessive features!!!!

I love genetics...
Cool fish, Tex Gal. I like the idea behind the glofish, but am not a fan of the commercialism.
The idea was that the fluorescent coloration was added to the fish to use them as indicators of polluted water. It's a cool idea, it's just too bad the company "creating" the glofish started making it illegal for anyone else to sell fluorescent fish.
), you may want to be careful! LOL.

I've never heard of a person getting in trouble for selling the ones they've bred, but I've never seen anyone try to online. Sooo... I dunno if your plans were to offer them eventually (that's always my plans for fish I breed...

Thanks Six. I'm actually enjoying their fry in my own tank. I wouldn't mind giving them to anyone. I know that the company says you can't sell. them. I would like to see if I can ever see a spotted one. I would really like to see them spotted. They breed all the time in my tank. You can't stop nature!

Really neat texgal! Impressive looking too.
My danios breed all the time, but I took them out and put them in the 130g community, so probably won't get any more fry from them.
I am now trying to breed the celestial pearl danio. We'll see how that goes.

Beautiful fish TG (ha, I covered both hubby and wife with that one... )! I had no idea the genes could carry back that way. Interesting info.
Supersmirky, I've heard that the CPD's are pretty easy to breed providing you put some sort of a grid covered with moss or whatever in the bottom of the tank for cover so the parents can't eat them.
I have mine in a bare bottom tank, so I'm just going to attach suction cups to the plastic needlepoint type grid and stick it to the glass on the floor, covered by some moss. I see some fry have already survived without it, but you might say that tank is overgrown with moss, so there's lots of cover already.

Yea, there's a guy in my fish club breeding the CPD by just pulling out water from the main tank, putting it into a bucket and seeing what hatches out. Pretty simple. I traded him some rainbows for some of his fry but haven't tried breeding them myself. GL!

nice pics I sold a purple danio like that out of a tank in my old fish store that someone pointed out to me cool stuff if they were easier to come by

Such a beautiful, flashy fish. I'd love to see a leopard version as well.

The hybrids are fertile. They have bred back. The next generation had some regular zebras (where did they come from?), red glo-lights, and some like the parents. The fewest were the regular zebras with teh glo-lights and dark red being 50/50 of the rest. I never tried the generation after that.
