Thanks for comments.
She has still only had the 4, and they are doing very well, eating white worms, bloodworms and daphnia.
They were about 25mm- 1 inch- long when born, so not too bad a size.
They are being housed individually to prevent legs getting mistaken for food shall we say!!
The adult female is still well rounded so hopefully there will be more, but im not worried if there isnt, i think my female gigliolli will be next to eanter the 'birthing pool'
