Knowing When Your Guppy is About to Deliver

Knowing When Your Guppy is About to Deliver


If you are really getting serious about your guppy breeding the first thing that you really need to do is start keeping records. You also have to become very intuitive as to what is happening with your guppies. As you begin to study your guppies you will become more aware of what is happening with them particularly for your pregnant guppies.
There is no doubt that you are filled with anticipation at the arrival of your new batch of fry and that you have put a great deal of work into making sure that their atmosphere is going to be perfect for their arrival. This means that once the female guppy has delivered you are going to want to remove her from the tank as the possibility exists that she will devour them. This means that you have to watch the time constraints especially If you are planning on being away during the delivery. Then you are going to have to make sure that someone is there to take care of the fry for you.
This means that you need to know what the date is going to be as close as possible. As you probably already know a guppy that is pregnant can carry her fry from anywhere from 21 to 30 days, however in many cases the delivery is done in 28 days. If you have been keeping good notes and know when you’re female guppy was impregnated then you will have a good expectation of the date of delivery. If you’re not quite sure then you can count from the date that you put her back into the breeding tank to expect her to give birth anywhere from 21 to 30 days following that day.
When you begin to really observe your guppies you may be able to actually see the fry inside the gravid spot of some of your guppies. This is more true with those that are lighter in color. It is easier to see the baby guppies in the blonde and light colored females. You won’t have this opportunity with the darker colored ones. You can observe this by watching the female when she swims close to the light and hopefully get a right angle where the light is behind her and shining on her stomach area. She will have to be remaining still in order for you to get a good view.
What you will see is in the gravid area some little tiny or dark dots. These only show in the latter part of the guppy’s pregnancy and what you’re actually seeing is the eyes of the babies. The closer they get to being born the more visible and well formed these black dots are.

After you have observed the same breeding guppy giving delivery a few times you will be much more astute to what her pattern is although this can change as she may deliver in 28 days one time and then 31 days at another, but it will give you a better insight as what to expect.
Making sure that you have some resources in your tank for the baby fry to hide among once that they are delivered if you don’t happen to be there will be something else that will help you save the fry and until you are able to remove the mom from the tank.


  1. I was wondering if there was any way to tell if my guppy moms were about to deliver now I know what to watch for.

  2. now I don’t feel so nervous about getting into breeding guppies, I didn’t realize how important it was to keep a calendar but it makes sense

  3. I really like the way you get the message you are delivering across in simple to understand terms, this is great for the novice guppy enthusiast
