Hi rbel, As a general rule, the females are much larger and if the frogs are the same size, they will be fatter. Another interesting thing to note is that the males will always seek the highest spot within the pond to croak, stand a stone upright in the margins and just quietly watch what happens, it seems to be the one with the best and loudest 'croak' gets first pick of the females. (probably to do with the fact that the biggest males croak best ) once this initial 'singing 'period is over and they pair up with the best males grabbing hold of a female, the lesser males often join in, ending up with one ball of spawning orgy HaHaHa, somtimes when there are few females, Ive seen males grab anything that moves, even fish, well, they say love is blind H
aHaHa, best wishes , Lannerman
