ive jst released a female guppy into a tank along wit other guppies (it was in a breeder) and the males started harassin it and they've got it pregnant is it goin to be k for the guppy to give birth
There's nothing to worry about. In my experience, guppies can breed from about a month old, onwards. They may become, "pregnant", but do not give birth until they're large enough to do so. 3 months old is quite old enough for a fish to give birth. Although, as has already be stated, she won't deliver many young.
