I volunteer at a pet shop and I got a 3ish year old female ball (she's right at 48") a few weeks ago, today a guy walked in and gave me a 1 year old (and some months) ball.

How do you think my adult female will take to having another, younger male in her tank? She's currently in a 20 gallon, and seems to be quite active, and yet docile at times as well.

I have a rather large water bowl in place, and good humidity. I know I'll need another hide, but other than that, what am I missing, or is this just a bad idea all together?
