Based on my own experiences, guppies from PETSMART do not give birth to as large groups when they do, which is rare.
Yes.
yes and wen they do it is best to put them in a seperate breeding tank and take her out as soon as she is finished as she will eat her own babies(fry)
The signs of guppy breeding is when the males (the more colorful fish) start chasing the female guppies (the duller ones). The female guppies should appear to become fatter, signifying that the fish is pregnant.
Only guppies breed with guppies naturally.
Breeding is easy but yet hard. All you need to do is get a boy and a girl guppy of course. If our going to have several guppies,then you don't get the same amount of boys and girls. You will also need a breeding net (choice) and a separate tank or lots of plants in the adult tank. The plants will allow the guppies to hide from the parents that will try to eat them.
They probably will not :( im breeding and that just might happen to my guppy so I'll let you know :) Answer = they will not as I am an experienced breeder.
YES! and without mutations. So, breeding once leads to hundreds of gubbies.
You could either sell some of your guppies so as they won't breed, sell the guppy babies you have online or at yur local pet store or keep one of your guppies in one of the seperator tanks you get for your main tank.
2 cm for males (when they get very colorful) females, a little bigger
Pearch and guppies
You will probably spend more than you make they don't make a very good profit.
Yes, but sometimes one might peck at the other.
