Yes to both.
Water monitors have a tendency to become more trusting and tolerant than many other species of monitors, but there is no guarantee. There is a very real chance you will end up with an 8 foot, extremely muscular, fast, and athletic lizard with razor sharp teeth and huge claws that is terrified of you and will do whatever it can to defend itself from your perceived aggression.
>>Where can I get some good monitor info. Like growth rate,
>>ect..
The Pro Exotics web site is a good place to start. If properly cared for, a water monitor can reach its full adult size within two years, and a reproductive size within a year. Most people do not care for them properly, though, and if you haven't had monitors before chances are you will make a number of mistakes with this animal before you figure out the tricks of keeping them. I hope you can learn quickly, and we (or at least I) here on this forum are happy to help you learn, let you know the tricks of the trade, and share our own mistakes so you will not have to repeat them.
>>Also whats the pros and cons of getting a male vs female.
It doesn't matter, since juveniles cannot be sexed at better than chance in any event. It will the the luck of the draw. If you want an animal that is most likely to end up being tolerant of your presence and interactions, start with a hatchling.
Having said that, males tend to be larger, more muscular, more trusting, bolder, and more aggressive. Females will be shyer, smaller, more slender, and more defensive. Either can make a good pet. Either can make a poor pet. Either can send you to the hospital in the blink of an eye if you make a mistake, possibly with permanently crippling damage.
>>I understand they can be alot of work. I usually only work
>>with boas and burmese pythons. Thanks
Monitors are very different from boas and pythons. Forget everything you think you know about reptiles that you learned from keeping snakes. It will not help. start with an open mind and learn how to keep monitors. If you apply husbandry appropriate for snakes to monitors, your monitor will languish for perhaps a few years before dying.
Having said that, one of the smartest and most tolerant and trusting monitors I've ever had was the one water monitor I cared for. That critter was scary-smart. He was also quite docile and a pleasure to work with. Sadly, water monitors just get too frikkin' big for me - there's no way I can give them the space they need (an adult will need at least a standard size bedroom converted into its enclosure).
Good luck,
