I have 2 males and 1 female A. Cacatuoides in a 20 gal and it seems that the female “temporarily” pairs up with the smaller male but he still ends up chasing her around. The ither male is much larger and clearly staked out his territory in a small cave. Whenever the other 2 approach his hide he always oushes them away. I believe the female is ready to breed or ar least pair up due to her prominent coloration but how do I tell if they pair up? Should I try removing either one of the males or females for a while?
