When I was young I had guppies. Females had a dark spot on their belly and then the belly grew and out they came, swimming.
It is unbelievable but I don't remember the time...I think females can even keep sperm inside of them for a lot of time and get pregnant out of that sperm for more than once...
well miguel i thought this fourum topic was about breeding and hopefully i can get a "monster" collection of guppys for now then move up and thanks for the info davo
guppy breeder when u see the gravid spot on the female turns really really dark (on dark colored female) or really really pink (on light colored females) it would be a couple of day before lil guppies pops out.
