We just added a new frog to the tank. He has been in there around 36 hours and was keeping to himself. Hippity-the male- tried mating with what i am assuming is a new female. However in the past hour he has taken the new frog-now named Lucy- and instead of grabbing the waste, he will only grab around the neck and drag Lucy into the water while strangling her. Now my question is, could this new frog-though quiet- be a male that hippity is trying to kill. It sounds stupid when i think about it, but im watching them now and Hippity is attacking the new frog.

If it's two males, can they live together in a 20 long or should i return the newest one?
