Wow great photo Phil! Darklands - are they around much anymore?
I think there are a few colonies of 'Darklands' still around. Doubt there are more than 1/2 dozen people that have them.
They - and that frog are Rich's (Rich Frye) line. 'Site specific' collected animals.
Now I have always, and still do, have 'Cauchero' which imo look exactly the same. The Panamanian 'Aguacate' penninsula is long and wide and produces some purple looking frogs and deep red and blues - to all blues and someone even said a black frog. Interesting.
