hello, my betta is nearly 3 month old now. i had jarred some fry that is nipping others, which i could tell is male. but i could not tell which is female as i cannot see the egg spot. do the female have to be older to see the egg spot?

please excuse me for my english

Not always, but the older they get the more pronounced it is as they reach maturity. You are going to want to look at the size/shape of the dorsal as well as the length of their ventral fins to help determine sex.

To add to the above, When young both sex often show eggspot, then the male's eventually disappears. So don't rely on eggspot when sexing. Also consider body form - males are often slimmer and longer with a bigger head and mouth (head looks blunt from above). While females look wider/fatter at the midsection, looks shorter and has smaller head with smaller mouth (head looks pointy from above.
