Yeah, they are expensive. I dont know of anyother freshwater species that looks similar to the Fly River turtle. I would just keep an eye out in the Kingsnake Classifieds...

I am currently in the US Navy, so unfortunetly I have sold off my collection of herps. But over the years have kept many different species of turtles, geckos, lizards, amphibs, and even fish. Looking forward to getting back in the hobby once im out though!
