Hey all 

its hard to judge scale of size but this female seems to be getting larger and larger fairly quickly… but is she holding fry?

She might have eggs. They are not livebearers like guppies though.

Thank you, if they have eggs does that mean that have been fertilised by a male?

Fertilisation happens outside of the females body.

As @TheSwissAquarist mentioned, they are fertilized outside (external fertilization). With livebearers, males have a specialized shell that allows them to transfer sperm packets to the female so she can fertilize eggs inside (internal fertilization) and carry them until she gives birth to developed babies.

If you want to try breeding egg scatterers, you can add in java moss for the eggs to collect in, or a spawning mop made of yarn or even "Easter grass." Then, you can separate parents from eggs and raise them up to have lots of babies OR keep it in the tank and maybe get the occasional baby fish.

I recommend trying to raise up fry at least once. You can learn a lot from the experience...and it's fun!
