Inbreeding does not produce defective traits in dart frogs. It is hypothesized that because many species have such limited ranges that inbreeding often occurs in the wild. Many of the frogs that are proliferated in the trade have come from only a few bloodlines imported 10-30 years ago and have been inbreeding ever since with no apparent problems. Many breeders have outsourced to acquire new bloodlines from Europe in order to add fresh bloodlines into the trade. We always keep documentation as to where we purchase the frogs, what lines we've bred them with, and where the breeder originally acquired them. I recommend asking your breeder whether the frogs have multiple bloodlines and if not, ask for recommendations about where you might acquire other bloodlines.
