From what I understand, most Senegals on the market are WC chams.
I would not recommend that you get any, unless you can get CB stock.
WC chams are not only prone to health problems (usually parasites/travel injuries), and often struggle to acclimatise to a captive environment (resulting in shortened lifespans and high vet bills), but by supporting the capture of wild animals you may be affecting the survival of the species.
