My female guppies keep showing signs of being pregnant (black gravid spot near the anal fin and large stomachs) but.... these symptons seem to fade each morning I keep an eye on my faux plant but cant see any fry (I even move some of the features but still nothing) how would I tell that these guppies are truely pregnant. I have 12 guppies 6 male and 6 female I know that it is highly unlikely for them not to be mating.. but there apears to be a lack of fry anywhere and it always seems to be a ghost pregnacy ... please !!!!!!

Would it be prudent to get a breeder????

many thanks in advance :)
