>>1. Where can I find a care sheet on them to see the specifics
>>of them. (I would assume it depends on what kind)
The basic care of all monitors is practically identical. I have a writeup on how I keep my argus monitors at www.pizards.com/hbd/tricks.html
>>2. What is a good monitor for someone wanting to get one.
>>
there are a bunch I like Nile (maybe to big),
Not a Nile. They not only get big, they are totally unsuitable for pets. They are paranoid, and few ever come to trust you. Expect a very large, very strong, very well armed lizard that will use every weapon in its arsenal to defend itself from you.
>>Peach Throat,
Never had one. I hear thay are somewhat high strung, but small enough to be managable. I expect they have somewhat higher humidity/water requirements than the monitors I am used to.
>>and Argus
One of my favorites. Lots of attitude, and their sheer intensity can be unnerving. They are fairly high strung and jumpy, but it is all bluff. They put on a big hiss and puff display but are reluctant to bite in self defense. They have an amazingly strong feeding response, like sharks in a feeding frenzy. Make sure no unarmored body parts can be reached by a lightning fast monitor with faster reflexes than yours when any food is present, and make sure the argus knows that there is no food around when you reach into its enclosure. The are beautiful, active, loads of fun to watch, have a penchant for getting into trouble, are amazingly hardy, and will keep you on your toes.
Other monitors to consider:
Ackies. These are sweet tempered, hardy, inquisitive little critters. Their small size makes keeping them much easier. Highly recommended for the beginner!
Desert sand monitors (aka flavies). These are simply the sweetest, most wonderful species of monitor I've ever had the privilige to work with. Like arguses in a smaller package and without the attitude and more discrimination about what they bite when food is present.
>>3. Size, My Iguana was only about 5ft and all tail and I had
>>him for 10 years before he passed away, so what are max sizes
>>on them.
Nile: 4 to 8 feet.
Peach Throats: about 3 feet, if I recall correctly.
Argus: males get 5 feet, females get 3 feet. Stocky and muscular, so relatively bulky for their length.
Ackie: about 1 to 2 feet.
Desert Sands: 3 feet.
Good luck,
Luke
