Males size is typically between 6.3 cm and 7.3 cm with some individuals reaching 9.3 cm. There is some variation based on species and overall care of captives. Females are usually between 10.8 cm and 12.7 cm depending on species and care as well.
Also, at this age you should have heard the frog call (croak) if male. Only males produce a mating call. Females just kind of make a grunt. Both are capable of producing the defensive scream.
