I recently bought some guppies from an aquatic shop.

They live in a 15 gallon (60 litre) aquarium all by them selves.

1 male and 2 females

The water is at 78 degrees and in the aquarium there is:

Heater
Pump
Filter
Gravel
Real plants
Fake plants
Light

The females love it.

I belive that I have a pregnant female.

She is quite small, still growing, but I have had them for 16 days.

She is round looking, cylinder type, but her gravid spot is black, no brown at all, all black. The gravid spot is neat and is about 3mm.

Like this picture:

identical for this one -

The black gravid spot is bigger and darker than this

They are completely identical to this

The questiona are:

How pregnant is she?
How long until she is due?
Any more info?

Thanks
