One website said that they are aggressive, and another website tells me that they are not aggressive, but can intimidate other species with their size so its better if they are put in with a more bold species.
Which one is more true? Is a male or female more prone to aggression, or are they both typically the same?
I read that cutthroats were aggressive but mine is such a wuss, I have to put him with my most gentle bird.

lol anyways, I was just wondering about some personal stories to help me figure out a housing plan for him/her. Who has Javas, and what are yours like?
