Guppy babies.

Hi y'all

Just a quickie - had a look around and can't see any information for this.

At what age to guppies become sexually mature?

Sometimes as early as 3 months. It depends if you have quickly developing males, or late developing ones. But yes, it can be pretty early.

I've got some guppies at the moment that are about 3 months old, and a couple of the males from the batch are chasing anything that moves around the tank, wiggling their "little boy bits" around, while some of the others completely ignore all the other fish.

I guess it can also depend on the fish...

I currently have 4 guppy fry about a week old...and they are growing up fast lol But I was wondering if I had to seperate the males from the females once they become sexually mature? If I dont will they inbreed with eachother? which i dont want at all

Yes, you do. Brothers and sisters will not hesitate to breed with each other, so it's best to seperate them as early as possible, to prevent them breeding. You can sometimes even sex them before 3 months. If you seperate them once they are sexually mature, some of them could have already bred.
