Alright, I'm bored, so I apologize cause I know this or similar topics have been covered before. I've searched, googled, binged, etc. and haven't found anything that answers my question, so here it goes. Are there any lizards out there that stay relatively small (18" or less) that are aquatic and actually swim? I'm not talking about they enjoy a soak every once in a while, but something that will actually dive down and use a decent sized water feature in it's enclosure. Any and all help is appreciated.
