Any Teachers tried Glofish Breeding?

I'm on a mission.

Rather than going back and forth about what people have heard and think they know to be true from the internet, fish clubs, and pet store rumor mills about sterilization or not, I'm looking for links and/or quotes that clarifies whether or not Glofish (decedents of genetically modified zebra danios) sold in stores can carry fertilized eggs and eventually produce fry.

Some links for what I'm talking about:

Has anyone received info from the company with a clear answer? The clearest I could find was this:

"As a last clarification, I would like to note that the restriction is only with regard to intentional breeding of the fish, not any independently occurring aquarium “romance”; I apologize if there was any confusion about this."

*Ya gotta love Lucy's comment in that thread about fishy birth control.

I'm going to fill out a request to raise and breed glofish next year for educational classroom purposes. It will be a great opportunity to help students learn about properly raising fish, their life and reproductive cycle, and so forth. It would be neat to raise unmodified zebra danios at the same time in a separate tank so students can chart the similarities and differences. (I'd been planning this with livebearers, but I think I'll modify that part.)
This is a link to a user on youtube. They have video of the glofish spawning and glofish fry and then the glofish when they get older as well.
My lfs had glofish that spawned. All the glofish were sold and left behind a surprise, lol!!! ;D They still tiny, not many. But they are neon pink ect.
Great link Cesch! I didn't even think of checking out YouTube!

*giggles* @ AlyeskaGirl. What were those naughty fishies up to!

That certainly answers my question and makes my lesson planning loads easier. *lol* This will be my first time with fish in the classroom. It should prove loads of fun and very educational.

...Though it's been SO hard having found good tank deals on CL and then having to leave them sitting empty in my garage.
*lol* Actually, I teach middle school ENGLISH!

But my classroom is very nontraditional. :;jk:;qu We grow plants and vegetables each year; this will be our first year of fish.

I really enjoy sharing my love of nature and animals with my students; it teaches them responsibility and lets them learn new things even when they're just having fun. It appeals to more learning levels and styles and stimulates their desire and appreciation for learning when it's something fun.

lol. Sorry, I can go on forever about teaching. I just love my students!
I assumed it was english, but then you mentioned fish. Lol - I got confused.

We watched the movies Soylent Green and Logan's Run in 7th grade Earth Science. That teacher was also a bit nontraditional.
Nontraditional pedagogy is becoming the norm for young teachers because so much research these days shows that the most important thing is to get students excited about learning. It's also a wonderful tool for my special needs students.

So long as my students keep showing higher than average test scores, my boss gives me plenty of room for creativity. I know I'm very lucky for that.
Very lucky indeed!! So many of my teachers just read out of the books and I was bored to death most of my school They were good at what they did just set in their ways. Now that I have children. (my oldest will be going to kindergarten next year) I value and respect teachers SOOOOO much more then I did when I was in school. All teachers are saints in my eyes and the great teachers (like yourself) just amaze me!!!. education is so important and when the teachers care and enjoy their jobs it shows and it makes a difference!. Thank you!!. Hopefully my kiddos will have some teachers like you!!.
My oldest is also going into Kinder next year, and already I can see how much of an influence the teacher has on his desire to learn.
As a parent, I have to agree-nontraditional methods work great with my daughter! I can always tell how a teacher teaches based on my daughter's grades. She struggled in Science through the 4th grade. She's aced it in 5th and 6th grades due to nontraditional teaching methods. Social Studies, too!
I have glofish fry in my tank right now. They breed like crazy just like other danios. It would be tough to keep them from breeding, it's just what they do.

Thanks couesfanatic. I've heard such different reports on whether or not they were fertile, I wasn't sure what to think.

It's going to be fun to see our first babies and to see how many of each color the fry end up being.

I'll definitely adjust the substrate and decor depending on whether we want eggs or fry after the first birth. I definitely don't want to produce more fry then I'll be able to care for.
I know this is an older post and what not but just letting you know, I believe that intentionally breeding glofish is illeagal

Well, it may be against company policy, and maybe they can sue you, especially if you sell them... but it isn't illegal. You can't be fined by the government or put into jail for it, I don't think.
It depend on which country you are in.
If you are in Thailand, they breed and sell them by the millions.
I'm glad to see that they are viable for breeding. I'm a high school science teacher (subject taught depends on year. Everything from Bio, Eco to Chem!) And I am planning a controlled spawn this summer with the classroom fish I brought home for the summer.

Since I AM an educator who will be using these in student experiments - there should be no legal issue. If all goes well they'll produce better than the guppies I've been using - and it'll give the students an even better 'industry' experience.

I have two pink females, one green female and two green males. Though the green ones are actually bright yellows. So I expect some cross breeding and it'll be interesting to see what colors are produced.
My biology teacher genetically made the glofish. The company he was working for threw him under the bus when he was finished and he received no credit and no money.

Yes glofish are fertile. But my teacher is going to change the genes to make them sterile. If anyone comes down to Florida you can take his genetic engineering and he shows his students how to "make" glofish.
