good beginner monitor or tegu?

[Skiploder]

I've been wanting to get a monitor or regular but I don't know what kind would be a good starter but before I do I would like to read as much as possible about them first and have everything ready for it before I can get it I have a few extra places to house them I have a display case that's about 5' long 3' wide and 2' tall I also have a room that was orignally built for iguanas but is empty and that's about 8' tall about 5' wide and 4' tall for anything that likes being in trees I can also get anything needed to house them if nothing I have is suitable. But I just want an idea of any or all beginner friendly monitors or tegus so I can research them and decide which I feel best suits me. Thanks for any help in advance.

"Beginner Friendly Monitor" is a misnomer.

While ackies stay small, they are not a beginner animal. They require care above and beyond what a regular snake or lizard needs. For example, that display case of yours is a good size for an ackie, but is virtually worthless if it does not have the ability to hold a deep substrate and keep humidity in.

The fact that you have the means to provide is fine - what is more important is that your have the knowledge to provide.

There a lot of people here who will give you advice regarding monitors lizards and their husbandry requirements - a couple them may actually know what they are talking about.
