I decided to put a male and female P.imp together today for breeding as they are now both mature enough. I've followed the same procedure as I always do, but these two have been fighting for four hours now. I use a piece of perspex to block the stings so no hits have landed yet, but it is like a boxing match. They go into their seperate hides for 10 min. then one will run over to the other and of they go again. I've never had a couple battle for more than 30 min before. I'm about to split them up again, has anyone else had a couple fight this long but eventually get along?
