They don't have a great reputation with healthy animals. I would definitely go with a breeder. Had I known what I know now about them I would've went a different way. Three cham I got is thriving, but he was a month old when I got him and he is definitely not a Sambava. I feel I got lucky.
I didn't get to finish my post and I apparently must have hit the button when setting my phone down to eat lol anyway I've never heard anyone have to pin bsfl only superworms due to bsfl being soft bodied and easily digestible.
