As far as I know, they are identical to regular zebra danios in an aquarium setting with all the needs, life expectancy, etc the same.

One LFS around here is now carrying "purple passion danios". They look to be a bit bigger than zebras, and are a pale purple/lavender color. I suspect they're another genetic alteration, maybe to giant danios.

I will report of any abnormailities of them, though like cobc said there aren't supposed to be any.

Could be that jsalemi, though I wouldn't want purple zebra danios, yellow and red are strange enough to get used to looking at.

As far as I know, the Purple Passion Danios are natural.

jsalemi

Really? I can't find a reference to them in any of the books I've looked in, including Axelrod's mini-encyclopedia.

Looking at the picture, I think what they're selling as "purple passion danios" are a hybrid of "blue danios".

I'm not a fan of hybrid fish or genetically modified fish. I equate this to Jurassic Park, only in real life. I mean....we do this to fish now, what's to stop us from doing it with other animals later? Nothing at all, because we've already broken through the moral implications. Fish are no different from dogs, cats, or people...The future is a very scary place, without adding scientists to the list of potential threats to our existence.

Science has always been both the boon and bane of mankind. Science and scientists are not in themselves evil -- it's what some people do with what science and scientists discover that becomes evil.

I was reading somewhere that thous fish are sterilized so they can not breed before they are put up for sale.
I am not sure how they would go about sterilizing them but my best guess and the way that would be the cheapest for the maker would have to be some kind of radiation.

DNA has LOTS of potential to do good ,but you can also say that the way things are ARE the way thing for a reason. The saying goes "If its not broke, don't fix it."

Well the fish do what they are supposed to do. I recently transfered my blue l.e.d. light and bought another one and put them in my 29gallon and under them the genetically altered fish DO glow quite well.

Gozer_1

That's just funny.

atmmachine816

Yes it's almost disturbing. I tried to get a picture but so far you can hardly tell they are glowing.

atmmachine816

Pictures of 29 gallon, glowfish, new angel, and l.e.d. lighting you can kind of seeing the yellow fish glowing here, it's hard to get my camera to pick it up so far.

i personly think that why change something that isn't broken. For example, what if we couldn't change the dna we would be happy with a regular zebra danio but since we know can change the dna us as humans with always want something new and eventually lead to a world full of cotaminated genes and problems because we as humans want somethings "new and unnatural!"

Well keep in mind that glofish were originally created to detect pollutants, not for marketing as aquarium fish. But I think you're absolutely right. It's a slippery slope for sure...first we create glofish for what seems to be a worthy purpose, but who knows what we'll be doing next.... Though that said, I still can't see anything inherently wrong with glofish specifically, although I wouldn't buy them myself.

neverendingninja

I have to agree with 0morrokh. I've seen them in several different LFS, and they always seem just the same as any other danios. I agree that messing with DNA is a scary thing, but you know...so was going to the moon. And, for that matter, so was crossing the oceans for the first time. People are always going to push the envelope, no matter the inherent risks. And it doesn't matter if us consumers buy into it, there will always be someone with a wallet thats a bit too heavy, and a mind that is a bit too curious.

You know, Columbus was bound to sail off the edge of the world...(I know, I know...he wasn't the first to cross the Atlantic...but I bet whoever did indeed do it first, probably peed their pants more than once on that trek)

With that said, I wouldn't buy GloFish, simply because they're not my style.

Look at human history and it's not hard to guess where playing with DNA will take us.

0morrokh

You can say that again.....
