What small lizard 'pairs' would do well in a 30gal gl aquarium?

have a 30gal terrerium setup with planted cacti and other plants. also will be adding a small goldengate bonsai tree. i already have most of what i need to house lizards. not a question abou what i need but what lizards do well in pairs in this sized enclosure. ive researched geckos do well but any other ideas, maybe something a little more 'exotic'...
