Thanks! I see you have added more pics to! They are all amazing looking chameleons! Monty is my pride and joy, having raised him form 7 weeks old, I was determined that he would survive to adulthood.
From my observations of him growing up (eventually!) I have a theory as to why they grow so slowly. From his weekly weight readings I found that his weight didn't increase by more than a couple of tenths of a gram per week until he got to the stage where he was eating feeders other than just fruit flies. I also think that being so active, it wasn't until he weaned off of flies that he actually consumed more calories than he burnt off and thus put on weight a bit faster. That is just my opinion from what I have witnessed, and may or may not be right, but it definitely makes sense to me!
