Update:

10:00 forced the issue and put both them in the breeder box with a divider between them. The smaller one shook vigorously overtime the bigger one charged.

3:30 I removed the divider and watched the smaller one shake, and the bigger one did not attack.

5:30 I decided to play with the variables and took the hairy shroom out and put it in the breeder box. Once it re-inflated, the bigger one seemed more aggressive. I took both clowns out and put them in the tank, leaving the shroom behind.

So far, they are both hanging out in the shroom's old spot. I see more shaking than before from the smaller one. I believe this is due to the fact that the female is not overly aggressive because her host is gone.

I'll keep you guys updated.
