Those females could´ve mated before they got to the lfs.Quick update, Fry found yesterday on return from shopping.
Sadly I was not quick enough to save the remaining few & they we're eaten.
Strange thing is I didn't notice any of the females were pregnant???
Yes they had darkened gravid spots but no other signs.
They are still juveniles & they are still in need of feeding up as I only got them on Friday afternoon from LFS, Sexes are never kept together either in the LFS but i guess transportation could of been mixed
