My guppies have just given birth and are now sitting in a breeder box. I'm only intrested in keeping a few males. Could anyone tell me how to tell the difference between them at one week old. thanks

Take a look at this, it might help:

but im not sure if you'll be able to tell at 1 week old. Someone else might be able to tell you.

I am pretty sure you won't know until about 6 weeks or so. What do you plan on doing with the others that you don't want?

It might be a while with the livebearers, even up to a few months until they show their gender. our platy fry are in a tank of their own until they're big enough to take to the LPS and they still all look like females.

Thanks. I'm going to ask my local pet store if they want the rest. hopefully they will (I know the owner quite well)

Yea, I think most shops will take them when they're an inch or more.
