Do your research, ask lots of questions, and then visit someone with a Rhino or other large lizard. I'm not going to tell you that keeping Rhinos is a walk in the park but I will say that they are my favorite Cyclura and are intelligent, interactive, amazing animals to keep.
They usually start out flighty and bitey, just like baby Green Iguanas. Most of them go thru a transformation right around the 2 year old mark. That's when they seem to realize that you are not a predator anymore, they are too large to be eaten by you, and they relax and calm down considerably (altho I have 2 15 month olds right now that have already reached this point). I can honestly say that I've never been tail-whipped by a Rhino but I have been bitten in handfeeding accidents and I'm glad they were just minor nips. An aggressive bite from an adult Rhino can cause some serious damage. My oldest male is 5 years old and I've yet to see any aggressive behavior from him during breeding season. My 6 year old female right now is a little over 4 feet long and weighs in at 16 pounds. I've heard of adult males weighing over 20 pounds.
I will agree with Joel that these are hardy animals and forgiving of most minor husbandry infractions. They can tolerate a wider range of temperatures than Green Iguanas and seem to be disease resistant. Mine thrive on varied diet suitable for Green Iguanas. UVB is a requirement. Keep in mind when you consider a Cyclura you are most likely making a lifelong committment. These guys live a long time, up to 50+ years.
Of all of my lizards, the Rhinos are the only ones that seem to seek out and really enjoy human interaction. My Rhinos are my most trustworthy and tolerant educational animals. We take them all over the state (and country LOL) for educational and conservation presentations. I've often said that if I were told that I could only keep one species I'd keep my Rhinos. I love my Greens, Cubans, hybrids, Tegus, and Monitors, but my Rhinos are definately my favorite.
Here's a few photos for you.


A friend with 2 of my Rhinos at Reptile Fest is Chicago '04

And just to show you the power of a Rhino bite..this went right thru the chin and broke the jaw bone. Loofah just had the wire removed yesterday
