bearded dragons are great pets. easy to keep. and look realy good. they dont get to big either. however, adult males can become extremely agressive. or sometimes remain perfectly tame. they are messy lizzards, and my dragon always smells realy bad when he "poops". thats the main problem with the bearded dragons in my opinion. they eat crickets or greens, such as collard greens, dandelion leaves, berries, or anything thats healthy for you.
another good choice is the leopard geckos. smaller size unless you buy one of those new giant morphs. they use the bathroom in a corner and keep their cages very clean. they are very tame and can come in a huge variety of colors. the young geckos dont like to be held however when they grow up, they will tolerate handeling very well. they eat crickets
another option is crested geckos, they eat fruit or crickets. there is a comercial food available, you can buy a large quantity of this product and have food for your little friend for a long time, its a complete diet that includes everything they need. but its always nice to include insects in their diet and give them babyfoods that are made from fruits. their cage should be heavily planted so they can hide otherwise they will become stressed. you may need to research more information with crested geckos as i have yet to have personal experience with them. im geting a pair this spring.
chameleons are fun. i bought a small veiled chameleon 4 years ago and he is doing great. they dont usualy get too big, are low priced and depending on the kind you get, can be very tame. the problems that come with these guys is they need plenty of water, large screen enclosure with lots of large plants, and plenty of uv light. i love watching my chameleon eat with his long tonge.
these are only a few of the options you have. and of course please research any reptile you are concidering from more than 4 dependable sites. each site says something different and may include useless information or information that may lead to problems. my discriptions are to give you the basic idea of each sugested reptile and i probly forgot to mention more details. i would recomend all of these reptiles, but since its your first, you should start with only one.
