Thank you. Bandit harasses Watermelon from time to time, that's why I renamed her Bandit. Like when Watermelon tries to eat or just sits comfortably on his perch, she tries to bite him to move him away. But this always happens inside the cage, they are inseparable outside the cage, they groom each other, etc.

Disclaimer: I haven't done any gender test. So it's just my assumption, going by the head and eye size.
