Glofish

[shentake]

hi there

anyone have experience, how to create your own glofish?

is it possible?

[Nanami]

do you mean those fish that has fluorescent dye injected into them to become glow in the dark fish?

I hope you understand the process which the fish would go through to become the so called glofish. many fishes are sacrificed meaninglessly in the painful experiments to create this so called glofish. it's artificial, it's cruel it's unnecessary and buying it helps perpetuate the cruelty behind this meaningless and useless "technology".

there's also a high chance that such fishes might not be able to live out their supposed lifespan. natural fishes are as beautiful if not more beautiful and why get cruel artificial beauties if you can easily get natural beautied?

It's sad to see how people don;t really care about the fauna when they consider buying fishes. It's always for personal without caring for the fish. My in laws bought some terrapins for my 3 year old daughter and then when one died they were like haha nevermind we just buy another one. I told them not to and released the surviving one.

i agree. it's really sad to see that people think that just because they are animals their lives are insignificant? i really disagree. even the smallest of life is never insignificant, even an ant will struggle to save it's own life.

the real glofish is a NUS product. I've seen the fishes real life, but it's not to be sold in Singapore due to the fact that it is genetically modified fish.

It is marketed in the US as glofish.
They injected jellyfish gene into the eggs of zebrafish. So the gene is manifested in the fishes.

It is a dominant trait. so if you breed it with normal zebrafish. at least half will be glofish.

I believe they are available in Singapore. I got some the other week as I thought they looked different in the LFS, it was only recently after a few weeks searching on internet to find out what they are that I identified them.

They exhibit behaviour very similar to the zebra danios

[Ingwe]

i think the ones you've got are likely to be the "golden" morph of zebra danios, not glofish, LFSs are not allowed to sell the genetically modified danios.

Perhaps they are the golden morphs but, to my eyes, they look pink with white stripes. Take a look at the attached, they are at top right of photo

[Ingwe]

yeah, my 8 danios look like that too. The females are of a deeper colour i think, my fuller bodied danios anyway. I'm not experienced with them though, are yours the same?

[43a57]

there is a chance that they may be illegally imported. or they might have been smuggled/given away from NUS itself.
years back I was allowed to offer a buying price for the 3rd or 4th generation progeny.

i searched the web, and there are cases where glofish is sold in canada, likely illegal import.

[Ingwe]

can we assume all reddish danios are genetically modified (vs selective breeding)?

there are two other color strains green and yellow, have not seen them on sale yet.

[Ingwe]

whether they are glofish or not will be obvious under black/actinic blue light.

i guess i'll hunt for black light to verify this..

these fishes are created for the purpose of genetic studies, and some kayu moron decided it would be good to sell to unsuspecting consumer with pedestrian taste.

please do not buy them, and if you have I would recommend euthanising in cold water rather than take chance of them being dumped into natural waterbodies.

[Ingwe]

I'll have to disagree with you here hwchoy, I'm not going to euthanise my perfectly healthy fish, I'd rather they live out their lives happily. (with no chance of being released into a natural body of water of course)

Cheers

[hwchoy]

its your fish, do what you want, just make sure they don't get out. remember these fish are fertile. although frankly they are not as disastrous as all the cichlids, natural or otherwise, that has been dumped into the catchment already.

[Ingwe]

yeah of course.

I'm just against the idea of euthanising healthy fish. Those walking catfish and snakeheads deformed by the dealers are another story.

yup. the cichlids have taken over much of our waterways now.

[wllm33]

although this is a sensitive topic, i do agree that we should not dump them into the environment , but i doubt they will even survive our environment , with so many predatory fishes lurking around our waters . imho , they won't last long in our waters , cos they will be fodder for the so many predators there.

[hwchoy]

technically "healthy" is debatable. as they are genetically modified, they shouldn't have left the labs. but then we have already created so many abominables I am not going to get very excited about this. the man-made flowerhorns and parrotfish are worst in my books.

wllm33, don't count on it. there are some thriving populations of Rasbora borapetensis in our longkangs, and as the name suggests, they belong to Lake Borapet in Thailand.

Provided genetically modified products, be it pet fish or fish for our consumption, has been tested and certified 'fit for purpose' then I don't quite see the problem, if it is for the overall benefit of mankind then it has to be good ... even if a few guys make a couple of bucks along the way.

Is there really a difference between a new breed of fish and a new model mobile phone. Not wishing to cheapen any debate, or appear disrespectful but at times, it is all about giving the punter what the punter wants, and trying to ensure nothing gets hurt along the way ... do we really want to stifle creativity and progress in the name of perceived 'righteousness'.

I bet the initiator of this thread did not expect such a wide and varied response to his question

As I said in an earlier post, I have purchased a few of these fish, I did not search them out, I selected them because I liked their colour, it took me over 4 weeks to finally identify them online ... and now it is suggested that I kill them. I can think of a few politicians that should perhaps receive such a fate because they might be of doubtful origins ... but an innocent fish

As to the question of whether or not unwanted fish should be placed in our local waterways, provided they are suited to the conditions, and do not upset the ecosystem ... why not. What is the difference between resettling fish, and resettling humans ... there are many places in the world that are now inhabited by non indigenous species, and most of them appear to be ok, so what is wrong with the fish.

Sorry if I have drifted slightly off topic, but sometimes, analogies help to explain situations and provide similar discussion points.
