I've never had any problems with Corn snakes in tanks. I would think that kind of set up would be perfect for them =). Then again I've never had any problems with tubes either. I guess it more or less depends on whether or not you're going to have it as a display animal or breeder.

I have my hatchling Corns in 10 gal tanks and there doing great! I have one 2 year old in a 20 long and its about perfect.

as long as it has several hides or substrate that it can burrow it should be fine in a 30.

Corn snakes are not nervous, I have 19 corn snakes and I think they are awesome snakes, none have ever acted nervous, even my newest babies are always happy to come out and hang out with me.  I keep them in racks to save space, I also have a couple T8's from Animal Plastics that I put the divider in that work great.  Corns only need a min of a 20 gallon tank, they would be prefectly find in a 30 gallon tank, I used to keep them in 20 gallon-40 gallon tanks, never had an issue with the tanks, but they are escape artists so make sure you have a very secure lid, on my 40 gallon breeder tank I use my boyfriend's guitar case, lol, but so far no one has escaped.  I always put a hide on the hot and cool side so they have a choice, I used to let my largest female have a stocking for a hide, it was actually due to a joke between me and my boyfriend, he used to walk around the house with her in his pocket and say she was his pocket pet, lol.  They're pretty easy to take care of, and most morphs are pretty cheap, unless you want a Tessera or a high white pie-sided.  If you have any questions once you get one don't hesistate to message me, I'd be happy to help you!

I think the floor space of a 30 is too much for a baby corn snake. A yearling maybe, or definitely an adult, but not a baby. You could always rear it for a bit in a tub to get some size on it, or you could just buy a yearling.

Why do you say that?

I've never understood why you "can't" or "shouldn't" keep a baby chondro in anything but a small tub, when in the wild they have a far more infinite space than we could provide for them in captivity. With appropriate coverage (lots of hidey holes), what is the harm?

Aaron, one of the biggest reasons that hatchlings are reluctant to eat is because of stress. Or that is the assumption. I think even with a lot of hidey-holes, the sheer amount of free space is a lot for a 6 gram corn snake. And if they go in to the aquarium eating well, they may revert just because of stress. I've never seen it in a corn, but I have heard of it. And I've seen it definitely in my hogs. It just isn't something I think I would recommend.

I've heard of it too, but it seems very strange that an animal would get stressed about space, I mean in the wild they have the whole world.  I half wonder if people just say stuff sometimes, I've never had any of my babies get stress in large spaces, but they're not in tanks, maybe the clear walls has an effect?

I can see if you put a 12g chondro in a 4' cube with one perch and high foot traffic. That I get.

But you put a 12g chondro in a lush 4' cube, with lots of areas to perch and hide and be comfortable, .. I dunno. I've just never agreed with the size of the cage being the issue on the "too big" size.. I'm sure it's easier for them to "forage" for food in a small space and find it, but in the wild they are active and search long and hard for something. And yes, I know they're not in the wild *yadda yadda ya* anymore. Just seems one of those things passed down as an easy answer with us not having really explored the benefits of larger caging thoroughly.
