Only thing i know about these is they may well be little fatter than the males and have a gold stripe look compared to the males.

Not easy.. and they are gen-mod fish so who knows.

Jase is right. Fish like that are hard to tell under normal conditions but when you add in dye injections and other modifications, it erases all the natural differences and you are stuck guessing based on size or breeding behavior

Females are much rounder, and well fat. Male fish are a bit skinner and just regular looking really. easier to tell in big numbers.

even if they did breed unless you separate the eggs and parents they'll eat the eggs.

Oh wait also most everybody was right! Females are more large, no offense but according to the fish, its true.

Males are less than a milimeter thick.Females are a milimeter thick.If a male and female glofish are together,they might eat thier eggs.Be prepared!

Glow fish are not dye injected they are genetic modified if they were to successfully breed and have eggs the babies will also be go fish that are bright and florescent no dyes used in glow fish

I think most male fish have different colored eyes while female have just black.

I have two Tetra Glowfish in my tank right now, and I have been researching for days trying to figure out if I have a male and female. One seems to be getting plump in the belly, I can attach pictures when I get home. Once I post the pics PLEASE ANYONE let me know if I have a male and female, and please also let me know if the purple one (which I think is female) is ready to lay eggs or not? I would really appreciate any feedback. Thanks!

Where does the eye colour idea come from ? I have never seen any Danios with eyes that were any colour but black, no matter which sex they are. The Glofish in these pics started out as Danios, though now they have no species designation, being genetically modified.

The red fish is a very good pic of a female, with the yellow one being equally representative of what the males look like, once they reach maturity. When they are younger it is very, very hard to see the differences. In the natural Danio that is not modified, the stripes are different colours in male and female and one or two other very minor characteristics are different too. But you can't see the stripe differences in the modified fish and the other things take some practice to see in normal fish, never mind the Glo fish.

Nobody can tell from a picture if a Danio is ready to lay eggs. If you read up on Danio breeding you will find out how to stimulate them, so they are likely to spawn. If you let them do so in their main tank, the eggs will mostly be eaten and fry that may hatch also will be mostly eaten.

It is much better to use a separate tank for breeding and egg laying, and remove the fish after they spawn.
There are dozens of articles on line about breeding Danio rerio which is what you need to know to breed them successfully. They are bred in the millions every year because they are used for lab research as well as wet pets.

We have 3 glo fish. I'm trying to determine male from female and was intrigued by the eye color comment. We have two with black eyes and one with green eyes.

Whether or not the fish are a pair, females can lay eggs if they want to. But unless a male then fertilizes them, they will not hatch.

Both sexes eat eggs and fry, assuming you got any fry, so chances of you ending up with new fish isn't very good at all. Often enough, a female will become full of eggs and then reabsorb them because conditions for mating and laying are not right. Rarely causes any problems.

And even if you get fry, few are likely to survive, because they need feeding with foods of suitable sizes. You might get one or two, but odds are against it.

Can't tell from those pics, and it's hard to tell anyway. They can't get pregnant. They are not livebearing fish.

IF you have a female, it may lay eggs, which would have to be fertilized by a male. Both parents will eat eggs and baby fish too. So it is very unlikely you will get any eggs from the Tetra Glofish you have.

Are either sex duller in color?
I have two and their colors are not vibrant at all.
I've had some 2 or 3 times in the past, and their colors were vibrant and they had yellow stripes.

Thank you! I did a lot of research on this because its just wrong to inject fish with dye. I know for a fact that they are genetically modified not injected.

A note to all who are concerned...

Glo-Fish are a trademarked fish that are genetically modified I beleive with jellyfish pigmentation.

Fruit Tetra are injected and often sold at places like Wal-Mart or other none dedicated pet stores.

I have kept both in the past, and still have a few Glo-Fish. I would not consider getting any more Fruit tetra as I feel it is wrong, but that is my opinion.

Here is a blog about written a while back that helps explain the difference, the biggest color and intensity of that color.

It seems like the green fish have green eyes
I have the same problem and I just wanted to know what gender they were.
Some people say eyes color
Some people say size
I'm kinda confused
