Ive had my big female close to 2 years and my smaller male (im assuming) about 4 or five months im thinking, im not really sure, I had thought they had already established dominance a while back as the smaller one would just sit there and twitch as the female come around and then they got along fine,even sharing the same nem. The last few days they have agressivley been cleaning a rock under the nem. And now tonight it looks like there trying to kill each other. they are both getting side by side and hitting each other with their tails and biting at each other. Both are staying very close to the nem and that rock and most of the time side by side. Are they still deciding dominance or are they mating or am i gonna wake up in the morning to a blood bath? ive never saw them act like this
