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.
NO! You have to spay or neuter your cat.
eats i belive it is also a way of comunicating with other guppies
impossible
Sorry, this is almost impossible. The only way to keep them from breeding is to keep them in a separate cage. or you could take away the nest and the material
This happens all the time. Female guppies can have a succession of litters after just one mating. You may see new fry several months after buying her from the pet store.
it is a way in which aliens have their tee
If the guppies are small enough the Betta will eat them.
no
Nope.
yeah you can do it on or off well that's what i think any way
guppies do not lay eggs the give birth to fry(baby guppies) and it depends on the environment it is in.. anywhere to 2-100.Guppies do not lay eggs. They give birth to live swimming young, like dolphins.
It is not possible for you to stop them from reproducing without doing something intrusive, however if you let the population curve peak it is highly likely that the environment that you provide them will stop supporting any further increase in population density. Its a bit cruel but I see your tank is overpopulated already, another way is to not separate the fry and let the fish feed on offspring thats what most aquarists do.
