well i find it depends on the size of the mother and the fry when born but if its your first lot it would be hard to tell if they a big or not. roughly how big would you say the fry and mother are?
am i doin sumthing rong lol all u seem to be having lots of fry, but my mollie had 5 and newest birth resulted in 6 (not sure which fish these were from lol) i want lots hehe
