bearded dragon vs hedgehog vs blue tongue skink vs leo gecko?

The hedgehog is a very different type of animal when compared to the other animals you are considering. Hedgehogs are very social and friendly. They like to snuggle. They are nocturnal. When they trust a person, they relax their quills enough so that they can be pet, held, and cuddled with.

Unfortunately, hedgehogs are often inbred, and therefore can be carriers of genetic diseases. There is a disease that many hedgehogs are afflicted by that is called "Wobbly Hedgehog Syndrome". Although the name sounds kind of funny, it's a terribly debilitating disease and it is heart-wrenching to watch your pet struggle through it. Hedgies will slowly lose the ability to control their limbs, and eventually will not be able to move at all. Soon, they will have to be put down, or else they will starve to death.

If you choose to get a hedgehog, get one from a reputable breeder who keeps track of the lineage of their stock. This prevents the spread of WHS carrying genes. Otherwise, adopt one from a shelter. Know that hedgehogs cannot just be left in a cage to be watched. They need social interaction.

Bearded dragons can get up to 20 inches, and therefore need a rather large enclosure (at least a 40 gallon long tank). Baby bearded dragons are rather fragile, and it isn't recommended to get specimens under 6 inches.
