No, but I do know that if they're captive raised, they're typically non-toxic, and one of the LFS in my area sells some. If I go the paludarium/terrarium route, these are beautiful and likely to be my first option for amphibians.
For those that aren't already aware, the toxins secreted by the poison dart frogs is a result of their native diet, where their prey items ingest certain alkaloids or some such.
