Ok, just make sure female is gravid (w/eggs) and ready to lay. The male will get frustrated and kill her if she's not ready. Eitherway, she will also get battered by the whole process. The male is going to wrap her around his body, and literally squeezed out the eggs, then take them one by one and spit it into the bubble nest and guard them and will again chase the female off and still try to kill her if he sees her. You need to keep an eye on them.
