We have 15 snakes at the moment. I promise, we're not horders I have been fascinated with all animals most of my life, including reptiles, especially snakes. I used to catch them when I was a kid. All of mine have their own enclosures. If you have similar species, and a large enough enclosure, you can keep them together, as long as they are close to the same size, and not a species prone to ophiophagy. But it is much easier to monitor the animals health if they are housed individually. They are pretty much solitary animals, so given enough space and with all of their needs met, they are fine to keep to themselves.
I've got some other pics of my snakes around here, and a thread with some pics of the rack I have most of the little ones in.
