New to owning a snake...couple questions

I just bought my first corn snake. He/she (not sure which it is) is about a foot long right now and in a 20 gal tank alone. I was considering getting a second in the same tank since their is so much room. I would like to know if they will 'play well together' or are they going to be battleing?
My second question is, it likes to bury itself in the aspen and I can never find the little guy. Once he is more use to the tank will he quit hiding so much or am i going to be on the hunt for him until he gets too big to bury himself?
Thanks for any advice.

Use the search engine to look up cohabit for all the reason NOT to put in another snake.
There is one of the main reasons...they will eat another snake and then you could have two dead snakes.
Beyond that...snakes are NOT social and would not like to live togeather.
Reasons of health, comfort, and more.... a ten second search will show you lots of good reasons not to...and not one reason besides being a cheapstake to do it.
ONE CAGE PER SNAKE is the rule!

Cohabitating generally is frowned upon as Tara noted above. Lots of reasons why not to do it and no real good reasons for it. Yes, there are some people who have done it successfully, but those are few and far between.

In regards to the aspen burrowing...it is natural. Some snakes outgrow it, some do not. I have some hatchlings that have never burrowed and some adults that still do.

i wouldn't say u should house two snakes together (but im not expert i only have the one corn but from experience the ppl on this site know what there talking about and wont lead u wrong ) . and the burrowing is natural my corn dose the same, sometimes she'l be in her hide sometimes under the aspen sometimes even up her trees

I use aspen for bedding as well. My snow corn can usually be found burrowed down to the glass when she isn't under her log or in her hide. The shelf she is on is steel and made of bars that allows me to see the bottom of the take, and as a result I can easily look underneath to find her when she is burrowed. Other than something like that, just keep digging gently till you find your lil friend.

You might be able to get your little guy to burrow less if you put as many hides in the tank as possible. They like to be hidden away and feel secure (there'd be loads of animals trying to hunt and eat them in the wild), so if he can't get as well hidden as he wants on the surface, he might be burrowing for security.

Hides don't have to be anything special - cardboard tubes from rolls of kitchen paper or old cereal boxes are fine (and disposable if they get pooped on).

On the other hand, you could just have a natural burrower!

And I agree with the others. One is the safest number for Corns.

Yeah, based on what I've read here it is not a good idea to cohabit corns. They like their alone time!

As for the burrowing, my snake does it too but usually it's only when I'm cleaning the vivarium and have already taken his hides out so it's easier to grab him. So try giving him a few more hidey holes and see if that helps.
