I recommend getting a fecal right away. Sometimes your Cham comes to you with parasites. They get parasites from the insects they eat and some parasites such as coccidia are highly contagious. I don't even wait 6 months on mine. We get fecals here every 3 to 4 months and 90% of the time somebody has something. If parasites go untreated eventually they will kill your Cham.
