Backwater reptiles isn't that good of a source for animals. Most, if not all places you'll find this species for sale are mass collected from the wild, and then sold to various stores, such as Backwater, LLL, and most people who have this species for sale. Most of those frogs don't do very well, due to the stress of shipping and oftentimes incorrect care during transit, so at that rate it would be better to have an enclosure already prepared, and to field collect a few of them. There is also a good care-guide for this species on this very website, if anyone needs it.
