i have 2 terrapins one is 5 inch and the other is 4 inch i dont know what sex they are they also keep shaking there claws towards each others head what does this mean
If they are the same age then the bigger one is female, they grow much quicker. The male will have a fatter and longer tail and noticably longer nails. The male will use his nails and feather them at the females cheeks, its done with mating, to show dominance, or to intiminate. since they are so young its prob over a corner of the tank or some food.
