The first number is males, the second number is females, and if there is a third number, it is unsexed. So I have 1 male and 1 female T. montium and 2 male T. quadricornis.
Usually, the reason why they are unsexed is because they are too young to tell, so the third number usually refers to babies that are too young to sex.
