My L-66 are succesfully spawning for the very first time, I'm so excited!

Anyway, now I have king tiger male guarding eggs, but I have a problem with the female. It is constantly trying to get to the cave with the male. I noticed yesterday that the female is trying to disturb the male by pushing him with his mouth. The male drove the female away. Today she tried to get to the cave by using pure force, without success. Half of her body was allready inside, but the male pushed her away!
What should I do? I'm afraid that the female might eat the fry when they come out of the cave?
