i got 2 ADFs this summer. my female died in september, so my male has been use to solitude for about 4 months. i just introduced him to a new female. the females have always been aggressive and a tad violent towards him... should i be concerned about this? could they actually hurt him? is there anything i should do? also, i would really like to breed them. i know that he has tried mating w/ my first female. this new one has not been in the tank long enough to get adjusted, but i really hope they will breed. are these frogs simple to breed, or more reluctant?
