I bought this juvenile 19 weeks ago from a guy on craigslist when it was just a very tiny froglet. The guy I purchased from said that the parents are "blue". I sought info on it and was told the color is normal in baby froglets and it will change with age. This frog still has the teal/cyan color to it months later, has peach toe pads and is only getting more beautiful with age. Could I have something here or is this normal?
