I just found a website that said that during the first month of breeding season males get agressive. Is this true?

Do you think I should get two so their not lonely? I do plan on giving them lots of attention though, and I dont work so I will be home with them. If I end up getting to do you think it is better to get two males or to females? and should they be in the same cage or seperate?

edit- I just read your post, thanks for the info.
