How do you know when your girl guppy is about o have a baby?

To tell if a pregnant guppy is about to give birth, there are a few signs to look for.

Signs:

1. Hiding away from other fish near the heater, filter, plants etc..

2. Loss of appetite (watch when you add food to the tank, she may just grab it then spit it back out).

3. Lack of energy. She may appear to just float around the bottom of the tank.

4. She will put her head down and her tail up. She will do this when she is about to start pushing etc..

5. You can also tell by her abdomen. It will be swollen and there should be a really dark (almost black, but for albino guppies bright pink/red) spot near her tail. This is called a gravid spot (which are actually the eyes of the fry inside her).

6. I noticed on my female, that a small white "dot" formed near the poop hole, a few hours before giving birth. This is her birthing canal opening!

If all else fails, you could place her in a breeding net or breeding trap for 24 hours and see what happens. If there are no fry, just release her back into the tank as the trap/net may stress her out.

You could also leave her in the main tank to give birth as long as there are plenty of hiding places for the fry. I use a mixture of dense leafed real and plastic plants. This isn't the best way to save ALL the fry but most should survive till you can scoop them out into a birth net/fry trap for proper safety.
