it may be a femake or a FAT guppy
All that is needed is a male guppy in with her.
like human that is pregnant.
Many male guppies have 'black spots' but if by "black spot" you mean "gravid spot" then no, a male guppy can not be 'gravid' because gravid is the equivalent of "pregnant" and male guppies can not get pregnant.
Under normal circumstances every female guppy you come across will be gravid (pregnant). My advice is don't worry about it she will be pregnant.
Your guppy will be pregnant if it has been in a container with a male since it reached maturity. A none pregnant guppy is an unusual thing. She will develop a belly and also when seen from behind she will have a dark spot visible deep inside her on either side of her vent. (the gravid spot)
Depending how old it is, if it is an adult female and it is in with male guppies then it is very likely that it is pregnant. (:
Well, since the females could be pregnant when you buy them, all male would be better.
yes if u look caarefully lol
If your female guppy has been in a tank/container with a male since it reached maturity it will be gravid (pregnant). Give it time. The fry will come eventually
I believe that female guppies can store male sperm in their bodies until the environment is just right and then they will use it to become pregnant at will.
If your female guppy is being or has been kept with a male then she will be 'gravid'. The colour of the 'gravid spot' varies.
No, unless a) the female fish got pregnant before the male died, or b) you buy a new male guppy and put him in with the female.
