What is herpafauna? Are you refering to Tom Crutchfield's old place (Herpetofauna, Inc.)? That place hasn't been running for many years as far as I know. Dwarf crocs are very occasionally available. Recently there were several hatchlings available from a breeder in Georgia and were sold for around $750. You will also need a captive bred wildlife permit if you purchase from out of state.
