No worries, i was prepared to answer about it.
I actually forgot Rosie (the boa) was in that picture.
The only other time I considered putting two snakes together was when I first received Romeo. I'd considered putting romeo in with valentine (which now, knowing romeo is indeed male... might have ended up with unwanted eggs. yikes!). I did a lot of research and decided that it wasn't worth the risk, and the only time I'd ever put any snake together was for breeding purposes (which won't be for many years yet for me!).
All that was before I joined sSnakeSs though. My snakes only ever meet outside of their homes and under close supervision, and not for long as most of the time they will slither away from each other. The other times.. Well I separate them cause it seems like Ashanti can get very interested in valentine, and I do NOT want breeding to happen. The last time I took them out I noticed the change in behavior and I am not taking more than one out at a time now.
(Change in behavior being that they wouldn't let each other go, although their tails never met they would use the ends of their bodies to hang on and refused to let go. They would also play 'follow the leader' with their heads, or go rubbing their noses up each others' bodies. i don't know if this is typical behavior when snakes are interested or not but I didn't want to chance it.)
