30 minutes is not enough. Once you have read for 5 or 10 or 500 solid hours about Monitors, not just your monitor but, in general as most information will help you from good sources. Then come back with your specific questions. It makes life easier for you and the people who try to help you.
I came here with ignorance blaring (no offense, just like yourself) and I quickly learned the extent of my mistake (getting a species that is not appropriate) and decided the animals do not deserve to suffer of my current inabilities.
So what is the best weapon against ignorance? Knowledge. How do you attain that often sought after emblem? Through trial and tribulation for one, or learning from other peoples’ mistakes and their successes (reading and asking questions). You will answer 99% of your questions with some solid reading of the forums, I guarantee it. You have to WANT to learn, and WANT to take the time to do it.
In short response to your question, most people try to feed their lizard’s everyday, as do I. If not directly then in-directly through leaving food in the enclosure available for them(crickets/dead rodents) when they want it NOT when you want them to want it.
While you are learning make sure your lizard has options in temperatures and a hot basking spot (at least 130 degrees SURFACE TEMP), and keep him fed well, the lizard will tell you when he is done eating, these animals are not ignorant like us. Do yourself a favor and don’t touch him until you fully understand what your responsibilities to the animal are going to be you are only going to complicate the learning process.
Goodluck,
Mike.
