Empty tank syndrome

Hey all,
I need some input on what to put into an empty 10 gallon tank. I'm wanting something cool-looking, active and won't outgrow this tank,preferably something I can handle, but I'm ok with a display/purely ornamental animal. We already have tree frogs, a frilled dragon and of course my pinstripe :) My BF is under the impression that a corn can be kept in one for it's entire life, but I think that's much too small for an adult corn. Anywho, what critter do you all think should go in a 10 gal?
I appreciate any and all suggestions!

It's definitely way too small for an adult corn. Maybe a sand boa? They stay relatively small, you can handle them, and they're fairly cheap. They also won't outgrow a 10gal, I don't think. They're little guys.

Rosy boas too! There are a variety of amphibians who could live in there too, though they aren't as handling friendly.

As far as snakes go the only two that can live in a 10g for their whole life I've heard of is a sand boa or a hognose. and it would have to be a male.

Ohhh, I second the Sand Boa, although I think a ten gallon would only be sufficient for a male. You could also get one Leopard Gecko, which is fairly interactive and you can handle it regularly - they have some really gorgeous morphs out there.

Have you considered leopard geckos or cresties?

Have to add my vote to the leopard gecko team as well, my boyfriend's daughter has one at our house and he's one of the most personable herps we own (he'll track me around the living room when it gets close to feeding time, super adorable)

Emperor scorpions!!

Tarantula!

Thanks for all the suggestions guys! I think we'll probably end up with a leopard or crestie, they do seem like personable little buggers :) Plus I've always wanted a gecko. Heck, I've got a tattoo of one, might as well get one to match lol.
Thanks again, and if anyone has an idea for something unique/ hasn't been mentioned, keep em coming!!!
