ok wright now i removed the divider as i found my male in the female part in this morning and she was chasing him and acting like biting so i think she started be aggressive and now he doesn't exit from that castle at all ....i am going to try feeding him pellets and sometimes few live foods ........( also it would be better to buy a bigger male ? ) and he will die by starvation as he doesn't exit from that castle as it is scared by the female and all the food gets in the females belly
