Something cool for my twenty gallon?

That tank needs a water change..

I was actually thinking about getting a rat.

scorpion, Scuba Hamster, Fire Belly Toad, Breeding mice to feed to fish, or build a snowman in your tank.

Ok abit on topic. Have you ever considered keeping ants? Just add some sand into the tank for them to make a mold. It would be cool to watch them moving in tunnels through the side of the tank.

Of course you will need to find some way to surround your tank with water. Else, INFESTATION!!!

Leos are by far the best/easiest lizards. You could try crested geckos, they require more humidity, and a different diet though. Not as personable as leos either.

Oh, Ants is a great idea, but I wouldn't keep them in a 20 gallon tank, probably a sterilite or tupperware container. In the spring you can find a young ant-queen before she settles down, and let her make a colony in your care. They are really awesome bugs!

Ants could be cool. I don't think they could scale the sides of the tank though. At least not the whole way. I might do that with the ten gallon I have laying around.

Ants can and do scale the walls of glass. You could buy some stuff from http://www.proexotics.com/store/product.php?productid=16230&cat=257&page=1

That's what I used when I was keeping roaches. A little bit goes a long way, worth the $$.

I might go with some small crabs and newts in the 20 gallon and then ants in my 10 gallon.
