What type of lizard is good for a 7 year old girl?

I would suggest you get a leopard gecko or a crested gecko as your first lizard pet. Both are low maintenance reptiles that have fairly good temperaments. They don't grow very large and don't require a big cage either. However, keep in mind that these lizards live for a very long time and require your time and dedication to live their entire life-spans.

other good first pet

- gargoyle gecko (care requirements are similar to those of a crested gecko)

- bearded dragon (great first pet if you can provide a large enclosure and the proper diet)

-geckos of the rhacodactylus genus (these geckos are great first lizard pets! The crested gecko and the gargoyle gecko are members of this genus. Other members of this genus include: leachianus, rough snouted, chaoua, sasorinum geckos. However, these geckos (with the exception of crested and gargoyle geckos) often command a hefty price.
