I got a few longfin danios awhile back, and now am looking for some glofish danios. Would like to put them outside by my steps in a smallish pond, with plants, ect. Would like to see if they will breed or not. I am not good with raising egg layers. What size would do for roughly 18-20 fish? Plus any babies they may produce?

Well... For 20 fish, I'd reccomend something in the 20-30g range. Just letting you know, the glofish will not be glowing in a pond... unless you have a blacklight over it, that is. They will probably spawn a lot, but fry will get eaten unless you take measures to prevent this. Technically, glofish fry are illegal and should be destroyed due to a copyright law. But that's not way too ethical. As long as you don't distribute the fry to people, you'll be fine. I've just got a couple questions.

Where are you located?

How long out of the year will they be outside?

Glofish don't breed true though. You may end up with glofish, or plain zebra danios if the info I read is correct.
If you mix colors they will be regular zebrafish... If the same color breeds together, they should theoretically breed true.

Hi
Sounds like an interesting idea, What kind of plants do you intend to keep many require a lot of sun so then you have heat problems so larger and deeper is much better. If you plan on the pool to provide food for the fry again larger is better because the fish will breed like flies lol
What about winter??? gary

Wouldn't it really depend upon whether the gene was dominant or recessive as to breeding true? Since this is a genetically engineered fish does anyone really know?

A bit different but citrus fruit is always grafted when a variety is discovered because the percentages of seed that breeds true is only about 25% with the same parents.

Can you get male and female GloFish? I've found that certain strains of fish I was after they only sold the male.
I've not read anything about needing to see the color under blacklight. The intensity seems to come from the amount of toxins in the water. The gene was spliced from a sea coral.

The difference between regular zebra danios and glofish are that researchers in Singapore added a fluorescence gene from a sea coral to zebra danio eggs to produce glofish. This gene causes the genetically modified fish to fluoresce or light up in the presence of environmental toxins.
They are patented/trademarked. Copyright is for written works.
Intentional breeding and/or any sale, barter, or trade, of any offspring of GloFishâ fluorescent ornamental fish is strictly prohibited.
Intentional breeding is of course illegal as per above. The and/or is the qualifier that just breeding is prohibited. Doesn't matter if you sell, trade or barter.

If glofish breed with other glofsh the babies will be glo fish. If they breed with regular zebra danios they will have the glofish coloring yet have zebra danio stripes. They will breed quite easily and both sexes are readily available. I'm not sure what happens if glofish breed with glofish of another color.

Anyway it sounds like a neat pond idea as long as the water stays warm enough for them. They can be a little sensitive.

Yes, the temp today was in the high 70s.I was thinking about a little kiddie pool filled with floating plants. And my long fin corys on the bottom for clean up and breeding. Should be able to get them outside within the month hopefully. Any babies will just be for my pleasure, then this fall will bring everytrhing in again.
