I have to agree with Ed. Last year I got a 1:2 trio from one of the top cham breeders, they were cb and 4 monthst later they all died within 2 weeks of each other. They were my first chams. I did everything "right", had been researching for months, lurked for awhile and then became active on this board, etc. etc. They went to the vet, I was in contact with the breeder, Dr. Ivan Alphonse, Dr. Sue Donoghue and we do not know what happened, there is speculation it was due to supplementing, but no one can know for sure. At the saem time another KS forum poster had a similar experience with a couple of hers (we got them about the same time) and I know she agrees with the vote for a bad choice for inexperienced cham owners. And to top that off I wouldn;t recommend buying them from a pet store. As Ed pointed out you are asking for unhealthy animals right from the get-go. Also, a cham should never be an impulse buy, there is a lot to know about their care in advance. If you are interested in learning more about chams in general see the sites below:
Don't mean to be so intense about it but I can just can't emphasize it enough after my awful experience. I now have a female veiled 10 months old and I love her - but again, this was all after lots of research (much of it on this very board).
